The most common treatment for XLA is an intravenous infusion of immunoglobulin (IVIg, human IgG antibodies) every 3–4 weeks, for life. IVIg is a human product extracted and pooled from thousands of blood donations. IVIg does not cure XLA but increases the patient's lifespan and quality of life, by generating passive immunity, and boosting the immune system. With treatment, the number and severity of infections is reduced. With IVIg, XLA patients may live a relatively healthy life. A patient should attempt reaching a state where his IgG blood count exceeds 800 mg/kg. The dose is based on the patient's weight and IgG blood-count.

Muscle injections of immunoglobulin (IMIg) were common before IVIg was prevalent, but are less effective and much more painful; hence, IMIg is now uncommon.Subcutaneous treatment (SCIg) was recently approved by the U.S. Food and Drug Administration (FDA), which is recommended in cases of severe adverse reactions to the IVIg treatment.

Antibiotics are another common supplementary treatment. Local antibiotic treatment (drops, lotions) are preferred over systemic treatment (pills) for long-term treatment, if possible.One of the future prospects of XLA treatment is gene therapy, which could potentially cure XLA. Gene therapy technology is still in its infancy and may cause severe complications such as cancer and even death. Moreover, the long-term success and complications of this treatment are, as yet, unknown.

Treatment in DOCK8 deficiency focuses on preventing and treating infections. Broad-spectrum antibiotics are a common mode of treatment when infection is present, though some infections (like lung abscesses) require surgical treatment. Pneumatocele may be treated with surgery, but the benefit is unclear.

Surgical treatment is also recommended for skin abscesses, along with topical and systemic antibiotics and antifungals.

Long-term treatment with systemic antibiotics, including trimethoprim/sulfamethoxazole, penicillins, and cephalosporins, is effective in preventing skin and lung infections. Other treatments used in DOCK8 deficiency include sodium cromoglycate, which improves white blood cell function, and isotretinoin, which improves skin condition.

Sometimes, Intravenous immunoglobulin is used as a treatment, but its benefits have not been proven. Levamisole is also ineffective. Mixed clinical outcomes have been found with interferon gamma and omalizumab. Though early research on hematopoietic stem cell transplantation was equivocal, later research has shown it to improve immune function. Two patients have been cured by bone marrow transplantation. Cyclosporine A is a current topic of research; preliminary results have shown it to be effective.

Treatment for X-linked SCID can be divided into two main groups, the prophylactic treatment (i.e. preventative) and curative treatment. The former attempts to manage the opportunistic infections common to SCID patients and the latter aims at reconstituting healthy T-lymphocyte function.

From the late 60s to early 70s, physicians began using "bubbles", which were plastic enclosures used to house newborns suspected to have SCIDS, immediately after birth. The bubble, a form of isolation, was a sterile environment which meant the infant would avoid infections caused by common and lethal pathogens. On the other hand, prophylactic treatments used today for X-linked SCID are similar to those used to treat other primary immunodeficiencies. There are three types of prophylactic treatments, namely, the use of medication, sterile environments, and intravenous immunoglobulin therapy (IVIG). First, antibiotics or antivirals are administered to control opportunistic infections, such as fluconazole for candidiasis, and acyclovir to prevent herpes virus infection. In addition, the patient can also undergo intravenous immunoglobulin (IVIG) supplementation. Here, a catheter is inserted into the vein and a fluid, containing antibodies normally made by B-cells, is injected into the patient's body. Antibodies, Y-shaped proteins created by plasma cells, recognize and neutralize any pathogens in the body. However, the IVIG is expensive, in terms of time and finance. Therefore, the aforementioned treatments only prevent the infections, and are by no means a cure for X-linked SCID.

Bone marrow transplantation (BMT) is a standard curative procedure and results in a full immune reconstitution, if the treatment is successful. Firstly, a bone marrow transplant requires a human leukocyte antigen (HLA) match between the donor and the recipient. The HLA is distinct from person to person, which means the immune system utilizes the HLA to distinguish self from foreign cells. Furthermore, a BMT can be allogenic or autologous, which means the donor and recipient of bone marrow can be two different people or the same person, respectively. The autologous BMT involves a full HLA match, whereas, the allogenic BMT involves a full or half (haploidentical) HLA match. Particularly, in the allogenic BMT the chances of graft-versus-host-disease occurring is high if the match of the donor and recipient is not close enough. In this case, the T-cells in the donor bone marrow attack the patient's body because the body is foreign to this graft. The depletion of T-cells in the donor tissue and a close HLA match will reduce the chances of graft-versus-host disease occurring. Moreover, patients who received an exact HLA match had normal functioning T-cells in fourteen days. However, those who received a haploidentical HLA match, their T-cells started to function after four months. In addition, the reason BMT is a permanent solution is because the bone marrow contains multipotent hematopoietic stem cells which become common lymphoid or common myeloid progenitors. In particular, the common lymphoid progenitor gives rise to the lymphocytes involved in the immune response (B-cell, T-cell, natural killer cell). Therefore, a BMT will result in a full immune reconstitution but there are aspects of BMT that need to be improved (i.e. GvHD).

Gene therapy is another treatment option which is available only for clinical trials. X-linked SCID is a monogenic disorder, the IL2RG gene is mutated, so gene therapy will replace this mutated gene with a normal one. This will result in a normal functioning gamma chain protein of the interleukin receptor. In order to transfer a functional gene into the target cell, viral or non-viral vectors can be employed. Viral vectors, such as the retrovirus, that incorporate the gene into the genome result in long-term effects. This, coupled with the bone marrow stem cells, has been successful in treating individuals with X-SCID. In one particular trial by Cavazzana-Calvo et al., ten children were treated with gene therapy at infancy for X-SCID. Nine of the ten were cured of X-SCID. However, about three years after treatment, two of the children developed T-cell leukemia due to insertion of the IL2RG gene near the LMO2 gene and thereby activating the LMO2 gene (a known oncogene). A third child developed leukemia within two years of that study being published, likely as a direct result of the therapy. This condition is known as insertional mutagenesis, where the random insertion of a gene interferes with the tumor suppressor gene or stimulates an oncogene. There is currently no approved gene therapy on the market, but there are many clinical trials into which X-SCID patients may enroll. Therefore, research in the field of gene therapy today and in the future is needed to avoid the occurrence of leukemia. In particular, research into the use of insulator and suicide genes is warranted as this may prevent cancer from developing. The insulator gene inhibits the activation of adjacent genes. On the other hand, the suicide gene is stimulated when a tumour begins to form, and this will result in the deactivation of the therapeutic gene. Moreover, the use of restriction enzymes such as the zinc-finger nuclease (ZFN) is being studied. The ZFN allows the researcher to choose the site of gene integration. Vector safety is important in the field of gene therapy, hence vectors that self-inactivate the promoter and enhancer (SIN) and adenoviruses that creates no immune response are prominent areas of research for vector biologists.

X-linked SCID is a known pediatric emergency which primarily affects males. If the appropriate treatment such as intravenous immunoglobulin supplements, medications for treating infections or a bone marrow transplant is not administered, then the prognosis is poor. The patients with X-linked SCID usually die two years after they are born. For this reason, the diagnosis of X-linked SCID needs to be done early to prevent any pathogens from infecting the infant.

However, the patients have a higher chance of survival if the diagnosis of X-linked SCID is done as soon as the baby is born. This involves taking preventative measures to avoid any infections that can cause death. For example, David Vetter had a high chance of having X-linked SCID because his elder sibling had died due to SCID. This allowed the doctors to place David in the bubble and prevented infections. In addition, if X-linked SCID is known to affect a child, then live vaccines should not be administered and this can save the infants life. Vaccines, which are pathogens inserted into the body to create an immune response, can lead to death in infants with X-linked SCID. Moreover, with proper treatments, such as a bone marrow transplant, the prognosis is good. The bone marrow transplant has been successful in treating several patients and resulted in a full immune reconstitution and the patient can live a healthy life. The results of bone marrow transplant are most successful when the closest human leukocyte antigen match has been found. If a close match is not found, however, there is a chance of graft-versus-host-disease which means the donor bone marrow attacks the patient's body. Hence, a close match is required to prevent any complications.

Serology (detection on antibodies to a specific pathogen or antigen) is often used to diagnose viral diseases. Because XLA patients lack antibodies, these tests always give a negative result regardless of their real condition. This applies to standard HIV tests. Special blood tests (such as the western blot based test) are required for proper viral diagnosis in XLA patients.

It is not recommended and dangerous for XLA patients to receive live attenuated vaccines such as live polio, or the measles, mumps, rubella (MMR vaccine). Special emphasis is given to avoiding the oral live attenuated SABIN-type polio vaccine that has been reported to cause polio to XLA patients. Furthermore, it is not known if active vaccines in general have any beneficial effect on XLA patients as they lack normal ability to maintain immune memory.

XLA patients are specifically susceptible to viruses of the Enterovirus family, and mostly to: polio virus, coxsackie virus (hand, foot, and mouth disease) and Echoviruses. These may cause severe central nervous system conditions as chronic encephalitis, meningitis and death. An experimental anti-viral agent, pleconaril, is active against picornaviruses. XLA patients, however, are apparently immune to the Epstein-Barr virus (EBV), as they lack mature B cells (and so HLA co-receptors) needed for the viral infection. Patients with XLA are also more likely to have a history of septic arthritis.

It is not known if XLA patients are able to generate an allergic reaction, as they lack functional IgE antibodies.There is no special hazard for XLA patients in dealing with pets or outdoor activities. Unlike in other primary immunodeficiencies XLA patients are at no greater risk for developing autoimmune illnesses.

Agammaglobulinemia (XLA) is similar to the primary immunodeficiency disorder Hypogammaglobulinemia (CVID), and their clinical conditions and treatment are almost identical. However, while XLA is a congenital disorder, with known genetic causes, CVID may occur in adulthood and its causes are not yet understood.

XLA was also historically mistaken as Severe Combined Immunodeficiency (SCID), a much more severe immune deficiency ("Bubble boys").A strain of laboratory mouse, XID, is used to study XLA. These mice have a mutated version of the mouse Btk gene, and exhibit a similar, yet milder, immune deficiency as in XLA.

Treatment is by parenteral administration of gamma globulins, either monthly intravenously, or, more recently, by weekly self-administered hypodermoclysis. In either case, mild allergic reactions (generalized pruritus, urticaria) are common, and are usually manageable with oral diphenhydramine.

In general, treatment for acquired partial lipodystrophy is limited to cosmetic, dietary, or medical options. Currently, no effective treatment exists to halt its progression.

Diet therapy has been shown to be of some value in the control of metabolic problems. The use of small, frequent feedings and partial substitution of medium-chain triglycerides for polyunsaturated fats appears to be beneficial.

Plastic surgery with implants of monolithic silicon rubber for correction of the deficient soft tissue of the face has been shown to be effective. False teeth may be useful in some cases for cosmetic reasons. Long-term treatment usually involves therapy for kidney and endocrine dysfunction.

Data on medications for APL are very limited. Thiazolidinediones have been used in the management of various types of lipodystrophies. They bind to peroxisome proliferator-activator receptor gamma (PPAR-gamma), which stimulates the transcription of genes responsible for growth and differentiation of adipocytes. A single report has suggested a beneficial effect from treatment with rosiglitazone on fat distribution in acquired partial lipodystrophy; however, preferential fat gain was in the lower body.

Direct drug therapy is administered according to the associated condition. Membranoproliferative glomerulonephritis and the presence of renal dysfunction largely determine the prognosis of acquired partial lipodystrophy. Standard guidelines for the management of renal disease should be followed. The course of membranoproliferative glomerulonephritis in acquired partial lipodystrophy has not been significantly altered by treatment with corticosteroids or cytotoxic medications. Recurrent bacterial infections, if severe, might be managed with prophylactic antibiotics.

Corticosteroids and immunoglobulins are two commonly used treatments for warm antibody AIHA. Initial medical treatment consists of prednisone. If ineffective, splenectomy should be considered.

If refractory to both these therapies, other options include rituximab, danazol, cyclosphosphamide, azathioprine, or ciclosporin.

High-dose intravenous immune globulin may be effective in controlling hemolysis, but the benefit is short lived (1–4 weeks), and the therapy is very expensive.

Infusions of immune globulin can reduce the frequency of bacterial infections, and G-CSF or GM-CSF therapy improves blood neutrophil counts.

As WHIM syndrome is a molecular disease arising from gain-of-function mutations in CXCR4, preclinical studies identified plerixafor, a specific CXCR4 antagonist, as a potential mechanism-based therapeutic for the disease. Two subsequent clinical trials involving a handful of patients with WHIM syndrome demonstrated that plerixafor could increase white blood cell counts and continues to be a promising targeted therapy.

A woman with spontaneous remission of her WHIM syndrome due to Chromothripsis in one of her blood stem cells has been identified.

In support of these studies, a 2014 phase I clinical trial treated 3 patients diagnosed with WHIM syndrome with plerixafor twice a day for 6 months. All three patients presented with multiple reoccurring infections before treatment and all had an increase in their white blood cell count post treatment. One patient (P3) had a decrease in his infections by 40% while the remaining 2 patients (P1 and P2) had no infections throughout the entirety of the treatment. Plerixafor may also proof to have anti-human papillomavirus (HPV) properties as all patients experienced a shrinkage or complete disappearance of their warts. While this treatment shows promise in treating neutropenia (decreased white blood cells), this trial showed no increase of immune globulins in the body. A phase III clinical trial has been approved to compare the infection prevention ability of plerixafor versus the current treatment of G-CSF in patients with WHIM.

The antibodies in ABO HDN cause anemia due to destruction of fetal red blood cells and jaundice due to the rise in blood levels of bilirubin a by-product of hemoglobin break down. If the anemia is severe, it can be treated with a blood transfusion, however this is rarely needed. On the other hand, neonates have underdeveloped livers that are unable to process large amounts of bilirubin and a poorly developed blood-brain barrier that is unable to block bilirubin from entering the brain.This can result in kernicterus if left unchecked. If the bilirubin level is sufficiently high as to cause worry, it can be lowered via phototherapy in the first instance or an exchange transfusion if severely elevated.

- Phototherapy - Phototherapy is used for cord bilirubin of 3 or higher. Some doctors use it at lower levels while awaiting lab results.

- IVIG - IVIG has been used to successfully treat many cases of HDN. It has been used not only on anti-D, but on anti-E as well. IVIG can be used to reduce the need for exchange transfusion and to shorten the length of phototherapy. The AAP recommends "In isoimmune hemolytic disease, administration of intravenousγ-globulin (0.5-1 g/kg over 2 hours) is recommended if the TSB is rising despite intensive phototherapy or the TSB level is within 2 to 3 mg/dL (34-51 μmol/L) of the exchange level . If necessary, this dose can be repeated in 12 hours (evidence quality B: benefits exceed harms). Intravenous γ-globulin has been shown to reduce the need for exchange transfusions in Rh and ABO hemolytic disease."

- Exchange transfusion - Exchange transfusion is used when bilirubin reaches either the high or medium risk lines on the normogram provided by the American Academy of Pediatrics (Figure 4). Cord bilirubin >4 is also indicative of the need for exchange transfusion.

In congenital FXII deficiency treatment is not necessary. In acquired FXII deficiency the underlying problem needs to be addressed.

After birth, treatment depends on the severity of the condition, but could include temperature stabilization and monitoring, phototherapy, transfusion with compatible packed red blood, exchange transfusion with a blood type compatible with both the infant and the mother, sodium bicarbonate for correction of acidosis and/or assisted ventilation.

- Phototherapy - Phototherapy is used for cord bilirubin of 3 or higher. Some doctors use it at lower levels while awaiting lab results.

- IVIG - IVIG has been used to successfully treat many cases of HDN. It has been used not only on anti-D, but on anti-E as well. IVIG can be used to reduce the need for exchange transfusion and to shorten the length of phototherapy. The AAP recommends "In isoimmune hemolytic disease, administration of intravenousγ-globulin (0.5-1 g/kg over 2 hours) is recommended if the TSB is rising despite intensive phototherapy or the TSB level is within 2 to 3 mg/dL (34-51 μmol/L) of the exchange level . If necessary, this dose can be repeated in 12 hours (evidence quality B: benefits exceed harms). Intravenous γ-globulin has been shown to reduce the need for exchange transfusions in Rh and ABO hemolytic disease."

- Exchange transfusion - Exchange transfusion is used when bilirubin reaches either the high or medium risk lines on the nonogram provided by the American Academy of Pediatrics (Figure 4). Cord bilirubin >4 is also indicative of the need for exchange transfusion.

In cases of Rho(D) incompatibility, Rho(D) immunoglobulin is given to prevent sensitization. However, there is no comparable immunotherapy available for other blood group incompatibilities.

Early pregnancy

- IVIG - IVIG stands for Intravenous Immunoglobulin. It is used in cases of previous loss, high maternal titers, known aggressive antibodies, and in cases where religion prevents blood transfusion. Ivig can be more effective than IUT alone. Fetal mortality was reduced by 36% in the IVIG and IUT group than in the IUT alone group. IVIG and plasmapheresis together can reduce or eliminate the need for an IUT.

- Plasmapheresis - Plasmapheresis aims to decrease the maternal titer by direct plasma replacement. Plasmapheresis and IVIG together can even be used on women with previously hydropic fetuses and losses.

Mid to late pregnancy

- IUT - Intrauterine Transfusion (IUT) is done either by intraperitoneal transfusion (IPT) or intravenous transfusion (IVT). IVT is preferred over IPT. IUTs are only done until 35 weeks. After that, the risk of an IUT is greater than the risk from post birth transfusion.

- Steroids - Steroids are sometimes given to the mother before IUTs and early delivery to mature the fetal lungs.

- Phenobarbital - Phenobarbital is sometimes given to the mother to help mature the fetal liver and reduce hyperbilirubinemia.

- Early Delivery - Delivery can occur anytime after the age of viability. Emergency delivery due to failed IUT is possible, along with induction of labor at 35–38 weeks.

Rhesus-negative mothers who have had a pregnancy who are pregnant with a rhesus-positive infant are offered Rho(D) immune globulin (RhIG) at 28 weeks during pregnancy, at 34 weeks, and within 48 hours after delivery to prevent sensitization to the D antigen. It works by binding any fetal red blood cells with the D antigen before the mother is able to produce an immune response and form anti-D IgG. A drawback to pre-partum administration of RhIG is that it causes a positive antibody screen when the mother is tested, which can be difficult to distinguish from natural immunological responses that result in antibody production. Without Rho(D) immunoglobulin, the risk of isoimmunization is approximately 17%; with proper administration the risk is reduced to less than 0.1-0.2%.

Most patients with hyper IgE syndrome are treated with long-term antibiotic therapy to prevent staphylococcal infections. Good skin care is also important in patients with hyper IgE syndrome. High-dose intravenous gamma-globulin has also been suggested for the treatment of severe eczema in patients with HIES and atopic dermatitis.

Hypergammaglobulinemia is a medical condition with elevated levels of gamma globulin.

It is a type of immunoproliferative disorder.

In a large number of phase I and phase II studies, autologous and allogeneic CIK cells displayed a high cytotoxic potential against a broad range of varying tumor entities, whereas side effects were only minor. In many cases, CIK cell treatment led to complete remissions of tumor burden, prolonged survival durations and improved quality of life, even in advanced disease stages.

Currently, the utilization of CIK cell treatment is restricted to clinical studies, but this therapeutic approach might also benefit patients as first-line treatment modality in the future.

Hypogammaglobulinemia is a type of primary immunodeficiency disease in which not enough gamma globulins exist in the blood (thus "" + "gamma" + "globulin" + ""). This entails that not enough antibodies exist, which impairs the immune system. Hypogammaglobulinemia is a characteristic of common variable immunodeficiency.

causes:

nephrotic syndrome

Dysgammaglobulinemia is a type of immune disorder characterized by a reduction in some types of gamma globulins, resulting in heightened susceptibility to some infectious diseases where primary immunity is antibody based.

It is distinguished from hypogammaglobulinemia, which is a reduction in "all" types of gamma globulins.

Hyper IgM syndrome can be considered a form of dysgammaglobulinemia, because it results from a failure of transformation from IgM production to production of other antibodies, and so the condition can be interpreted as a reduction of the other types.

Gastroesophageal reflux disease (GERD) is the indirect result of many factors and some autoimmune diseases like schleroderma. GSE can cause inflammation and delayed gastric emptying, which can persist through most of the sleeping hours causing GERD. GSE is associated with an increase of food allergies, in some patients this can cause diarrhea, but in others constipation. In some patients, food allergies and GERD are an apparent symptom of GSE, but these allergies and GERD often persist on a GF diet. While GERD associated with GSE can be treated with acid blockers, it is most effectively treated with proper eating habits and elimination diet. The more powerful

acid blockers (omeprazole, esomeprezole) can interfere with calcium adsorption and can aggravate preexisting hypocalcaemia and hypomagnesemia, which are more common GSE

Hypergammaglobulinemia is a condition that is characterized by the increased levels of a certain immunoglobulin in the blood serum. The name of the disorder refers to an excess of proteins after serum protein electrophoresis (found in the gammaglobulin region).

Most hypergammaglobulinemias are caused by an excess of immunoglobulin M (IgM), because this is the default immunoglobulin type prior to class switching. Some types of hypergammaglobulinemia are actually caused by a deficiency in the other major types of immunoglobulins, which are IgA, IgE and IgG.

There are 5 types of hypergammaglobulinemias associated with hyper IgM.

MeSH considers hyper IgM syndrome to be a form of dysgammaglobulinemia, not a form of hypergammaglobulinemia .

Other therapeutic interventions include:

- ethosuximide and other anticonvulsant drugs

- GHB receptor antagonist NCS-382

- GABA receptor modulators

- uridine

- acamprosate

- dopaminergic agents

- dextromethorphan

- glutamine

- antioxidants

- Lamotrigine

The GABA(B) receptor antagonist, SGS-742, is currently being tested as a potential therapeutic in an NIH phase II clinical trial (NCT02019667).

There is no standard therapy for multicentric Castleman disease. Treatment modalities change based on HHV-8 status, so it is essential to determine HHV-8 status before beginning treatment. For HHV-8-associated MCD the following treatments have been used: rituximab, antiviral medications such as ganciclovir, and chemotherapy.

Treatment with the antiherpesvirus medication ganciclovir or the anti-CD20 B cell monoclonal antibody, rituximab, may markedly improve outcomes. These medications target and kill B cells via the B cell specific CD20 marker. Since B cells are required for the production of antibodies, the body's immune response is weakened whilst on treatment and the risk of further viral or bacterial infection is increased. Due to the uncommon nature of the condition there are not many large scale research studies from which standardized approaches to therapy may be drawn, and the extant case studies of individuals or small cohorts should be read with caution. As with many diseases, the patient's age, physical state and previous medical history with respect to infections may impact the disease progression and outcome.

Avitaminosis. Avitaminosis caused by malabsorption in GSE can result in decline of fat soluble vitamins and vitamin B, as well as malabsorption of essential fatty acids. This can cause a wide variety of secondary problems. Hypocalcinemia is also associated with GSE. In treated GSE, the restrictions on diet as well as reduced absorption as a result of prolonged damage may result in post treatment deficiencies.

- Vitamin A – Poor absorption of vitamin A has been seen in coeliac disease. and it has been suggested that GSE-associated cancers of the esophagus may be related to vitamin A deficiency

- Folate deficiency – Folate deficiency is believed to be primary to the following secondary conditions:

- Megaloblastic anemia

- Calcification of brain channels – epilepsy, dementia, visual manifestations.

- B deficiency. Vitamin B deficiency can result in neuropathies and increases in pain sensitivity. may explain some of the peripheral neuropathies, pain and depression associated with GSE.

- B deficiency

- Megaloblastic anemia

- Pernicious anemia

- Vitamin D deficiency. Vitamin D deficiency can result in osteopenia and osteoporosis

- Hypocalcemia

- Vitamin K – Coeliac disease has been identified in patients with a pattern of bleeding that treatment of vitamin K increased levels of prothrombin.

- Vitamin E – deficiency of vitamin E can lead to CNS problems and possibly associated with myopathy

Mineral deficiencies. GSE is associated with the following mineral deficiencies:

- Calcium – Hypocalcemia causing Oesteopenia

- Magnesium – hypomagnesemia, may lead to parathyroid abnormalities.

- Iron – Iron deficiency anemia

- Phosphorus – hypophosphatemia, causing Oesteopenia

- Zinc – Zinc deficiencies are believed to be associated with increased risk of Esophagus Carcinoma

- Copper – deficiency

- Selenium – deficiency – Selenium and Zinc deficiencies may play a role increasing risk of cancer. Selenium deficiency may also be an aggravating factor for autoimmune hyperthyroidism (Graves disease).

Blood factors

- Carnitine – deficiency.

- Prolactin – deficiency (childhood).

- homocysteine – excess.

Children with DOCK8 deficiency do not tend to live long; sepsis is a common cause of death at a young age. CNS and vascular complications are other common causes of death.

There is no treatment known to slow or stop the progression of the neurologic problems. Treatment of A-T is symptomatic and supportive. Physical, occupational and speech therapies and exercise may help maintain function but will not slow the course of neurodegeneration. Therapeutic exercises should not be used to the point of fatigue and should not interfere with activities of daily life. Certain anti-Parkinson and anti-epileptic drugs maybe useful in the management of symptoms, but should be prescribed in consultation with a neurologist.
