Liver transplantation has proven to be effective for ATTR familial amyloidosis due to Val30Met mutation.

Alternatively, a European Medicines Agency approved drug Tafamidis or Vyndaqel now exists which stabilizes transthyretin tetramers comprising wild type and different mutant subunits against amyloidogenesis halting the progression of peripheral neuropathy and autonomic nervous system dysfunction.

Currently there are two ongoing clinical trials undergoing recruitment in the United States and worldwide to evaluate investigational medicines that could possibly treat TTR.

The aggregation of one precursor protein leads to peripheral neuropathy and/or autonomic nervous system dysfunction. These proteins include: transthyretin (ATTR, the most commonly implicated protein), apolipoprotein A1, and gelsolin.

Due to the rareness of the other types of familial neuropathies, transthyretin amyloidogenesis-associated polyneuropathy should probably be considered first.

"FAP-I" and "FAP-II" are associated with transthyretin. (Senile systemic amyloidosis [abbreviated "SSA"] is also associated with transthyretin aggregation.)

"FAP-III" is also known as "Iowa-type", and involves apolipoprotein A1.

"FAP-IV" is also known as "Finnish-type", and involves gelsolin.

Fibrinogen, apolipoprotein A1, and lysozyme are associated with a closely related condition, familial visceral amyloidosis.

There is no standard course of treatment to slow or stop the progression of the disease. sIBM patients do not reliably respond to the anti-inflammatory, immunosuppressant, or immunomodulatory medications. Management is symptomatic. Prevention of falls is an important consideration. Specialized exercise therapy may supplement treatment to enhance quality of life. Physical therapy is recommended to teach the patient a home exercise program, to teach how to compensate during mobility-gait training with an assistive device, transfers and bed mobility.

Kiacta - (eprodisate disodium) is in 2015 being evaluated as a protector of renal function in AA amyloidosis. Kiacta, inhibits the formation and deposition of the amyloid A fibrils into the tissues.

There is evidence that eating amyloid fibers may lead to amyloidosis. This evidence is based on studies in cattle, chickens, mice, and cheetahs. Thus, in a sense, SAA amyloidosis may be considered a contagious disease, although whether this occurs or is important in the development of naturally occurring amyloidosis remains unknown. Nevertheless, because amyloid fibers can be detected in muscle in low amounts, it raises some concern about whether people could develop amyloidosis as a result of ingesting meat from an animal with the disease.

When sIBM was originally described, the major feature noted was muscle inflammation. Two other disorders were also known to display muscle inflammation, and sIBM was classified along with them. They are dermatomyositis (DM) and polymyositis (PM) and all three illnesses were called idiopathic (of unknown origin) myositis or inflammatory myopathies.

It appears that sIBM and polymyositis share some features, especially the initial sequence of immune system activation, however, polmyositis comes on over weeks or months, does not display the subsequent muscle degeneration and protein abnormalities as seen in IBM, and as well, polymyositis tends to respond well to treatments, IBM does not. IBM is often confused with (misdiagnosed as) polymyositis. Polymyositis that does not respond to treatment is likely IBM.

Dermatomyositis shares a number of similar physical symptoms and histopathological traits as polymyositis, but exhibits a skin rash not seen in polymyositis or sIBM. It may have different root causes unrelated to either polymyositis or sIBM.

The drug tafamidis has completed a phase II/III 18-month-long placebo controlled clinical trial

and these results in combination with an 18-month follow-on study demonstrated that Tafamidis or Vyndaqel slowed progression of FAP, particularly when administered to patients early in the course of FAP. This drug is now approved by the European Medicines Agency.

The US Food and Drug Administration's Peripheral and Central Nervous System Drugs Advisory Committee rejected the drug in June 2012, in a 13-4 vote. The committee stated that there was not enough evidence supporting efficacy of the drug, and requested additional clinical trials.

Treatment depends on the type of amyloidosis that is present. Treatment with high dose melphalan, a chemotherapy agent, followed by stem cell transplantation has showed promise in early studies and is recommended for stage I and II AL amyloidosis. However, only 20–25% of people are eligible for stem cell transplant. Chemotherapy and steroids, with melphalan plus dexamethasone, is mainstay treatment in AL people not eligible for transplant.

In AA, symptoms may improve if the underlying condition is treated; eprodisate has been shown to slow renal impairment by inhibiting polymerization of amyloid fibrils.

In ATTR, liver transplant is a curative therapy because mutated transthyretin which forms amyloids is produced in the liver.

People affected by amyloidosis are supported by multiple organizations, including the Amyloidosis Foundation, Amyloidosis Support Groups Inc., and Amyloidosis Australia, Inc.

Median survival for patients diagnosed with AL amyloidosis was 13 months in the early 1990s, but had improved to c. 40 months a decade later.

The most effective treatment is autologous bone marrow transplants with stem cell rescues. However many patients are too weak to tolerate this approach.

Other treatments can involve application of chemotherapy similar to that used in multiple myeloma. A combination of melphalan and dexamethasone has been found effective in those who are ineligible for stem cell transplantation, and a combination of bortezomib and dexamethasone is now in widespread clinical use.

Amyloidosis is a group of diseases in which abnormal protein, known as amyloid fibrils, builds up in tissue. Symptoms depend on the type and are often variable. They may include diarrhea, weight loss, feeling tired, enlargement of the tongue, bleeding, numbness, feeling faint with standing, swelling of the legs, or enlargement of the spleen.

There are about 30 different types of amyloidosis, each due to a specific protein misfolding. Some are genetic while others are acquired. They are grouped into localized and systemic forms. The four most common types of systemic disease are light chain (AL), inflammation (AA), dialysis (AβM), and hereditary and old age (ATTR).

Diagnosis may be suspected when protein is found in the urine, organ enlargement is present, or problems are found with multiple peripheral nerves and it is unclear why. Diagnosis is confirmed by tissue biopsy. Due to the variable presentation, a diagnosis can often take some time to reach.

Treatment is geared towards decreasing the amount of the involved protein. This may sometimes be achieved by determining and treating the underlying cause. AL amyloidosis occurs in about 3–13 per million people per year and AA amyloidosis in about 2 per million people per year. The usual age of onset of these two types is 55 to 60 years old. Without treatment, life expectancy is between six months and four years. In the developed world about 1 per 1,000 people die from amyloidosis. Amyloidosis has been described since at least 1639.

No drug has been shown to be able to arrest or slow down the process of this condition. There is promise that two drugs, tafamidis and diflunisal, may improve the outlook, since they were demonstrated in randomized clinical trials to benefit patient affected by the related condition FAP-1 otherwise known as transthyretin-related hereditary amyloidosis. Permanent pacing can be employed in cases of symptomatic slow heart rate (bradycardia). Heart failure medications can be used to treat symptoms of difficulty breathing and congestion.

Because lack of sialic acid appears to be part of the pathology of IBM caused by GNE mutations, clinical trials with sialic acid supplements, and with a precursor of sialic acid, N-Acetylmannosamine, have been conducted, and as of 2016 further trials were planned.

In the absence of a liver transplant, FAP is invariably fatal, usually within a decade. The disadvantage of liver transplantation is that approximately 10% of the subjects die from the procedure or complications resulting from the procedure, which is a form of gene therapy wherein the liver expressing wild type and mutant TTR is replaced by a liver only expressing wild type TTR. Moreover, transplanted patients must take immune suppressants (drugs) for the remainder of their life, which can lead to additional complications. In late 2011, the European Medicines Agency approved the transthyretin kinetic stabilizer Tafamidis or Vyndaqel discovered by Jeffery W. Kelly and developed by FoldRx pharmaceuticals (acquired by Pfizer in 2010) for the treatment of FAP based on clinical trial data. Tafamidis (20 mg once daily) slowed the progression of FAP over a 36-month period and importantly reversed the weight loss and muscle wasting associated with disease progression.

A 2009 review noted that muscle weakness usually begins after age 20 and after 20–30 years, the person usually requires a wheel chair for mobility. There was no mention of increased mortality.

The aim in cerebral amyloid angiopathy is to treat the symptoms, as there is no current cure. Physical and/or speech therapy may be helpful in the management of this condition.

Exercise is a promising mechanism of prevention and treatment for various diseases characterized by neuroinflammation. Aerobic exercise is used widely to reduce inflammation in the periphery. Exercise has been shown to decreases proliferation of microglia in the brain, decrease hippocampal expression of immune-related genes, and reduce expression of inflammatory cytokines such as TNF-α.

Although not based on a human clinical trial, the only currently accepted disease-modifying therapeutic strategy available for familial amyloid cardiomyopathy is a combined liver and heart transplant. Treatments aimed at symptom relief are available, and include diuretics, pacemakers, and arrhythmia management. Thus, Senile systemic amyloidosis and familial amyloid polyneuropathy are often treatable diseases that are misdiagnosed.

In 2013, the European Medicines Agency approved the drug tafamidis (Vyndaqel) to slow the progression of familial amyloid polyneuropathy, a related disease caused by TTR aggregation that first presents as an autonomic and/or peripheral neuropathy (later progressing to a cardiomyopathy).

There has too little experience on the treatment of LECT2 amyloidosis to establish recommendations other than offering methods to support kidney function and dialysis. Nonetheless, it is important to accurately diagnose ALECT2-based amyloid disease in order to avoid treatment for other forms of amyloidosis.

The condition is suspected in an elderly person, especially male, presenting with symptoms of heart failure such as shortness of breath or swollen legs, and or disease of the electrical system of the heart with ensuing slow heart rate, dizziness or fainting spells. The diagnosis is confirmed on the basis of a biopsy, which can be treated with a special stain called Congo Red that will be positive in this condition, and immunohistochemistry.

There is no current cure for superficial siderosis, only treatments to help alleviate the current symptoms and to help prevent the development of further symptoms. If a source of bleeding can be identified (sources are frequently not found), then surgical correction of the bleeding source can be performed; this has proved to be effective in halting the development of further symptoms in some cases and has no effect on symptoms that have already presented.

Patients with superficial siderosis are often treated with deferiprone, a lipid-soluble iron chelator, as this medication has been demonstrated to chelate iron in the central nervous system.

While on this drug you will need a frequent blood test (weekly) to keep an eye on the blood levels as this drug is known to lower certain blood levels such as the neutrophils and WBC (white blood count) and etc. While it is ok if these levels go low in the average person, if they go low while taking Deferiprone Ferriprox it can cause life threatening infections that can result in death.

Alleviation of the most common symptom, hearing loss, has been varyingly successful through the use of cochlear implants. Most people do not notice a large improvement after successful implantation, which is most likely due to damage to the vestibulocochlear nerve (cranial nerve VIII) and not the cochlea itself. Some people fare far better, with a return to near normal hearing, but there is little ability to detect how well a person will respond to this treatment at this time.

Based on studies conducted in the United States, the prognosis for individuals with ALECT2 amyloidosis is guarded, particularly because they are elderly and their kidney disease is usually well-advanced at the time of presentation. End-stage renal disease develops in 1 out of 3 patients and has a median renal survival of 62 months. A suggested prognostic tool is to track creatinine levels in ALect2 patients. The attached Figure gives survival plotss for individuals with LECT2 renal amyloidosis and serum creatinine levels less than 2 mg/100 ml versus 2 mg/100 ml or greater than 2 mg/100 ml. The results show that afflicted individuals with lower creatinine levels have a ~four-fold higher survival rate.

Paresthesia or "persistent anesthesia" is a transient or potentially permanent condition of extended numbness after administration of local anesthesia and the injected anesthetic has terminated.

Potential causes include trauma induced to the nerve sheath during administration of the injection, hemorrhage about the sheath, type of anesthetic used, or administration of anesthetic potentially contaminated with alcohol or sterilizing solutions.

Medications offered can include the immunosuppressant prednisone, intravenous gamma globulin (IVIG), anticonvulsants such as gabapentin or Gabitril and antiviral medication, depending on the underlying cause..

In addition to treatment of the underlying disorder, palliative care can include the use of topical numbing creams, such as lidocaine or prilocaine. Care must be taken to apply only the necessary amount, as excess can contribute to the condition. Otherwise, these products offer extremely effective, but short-lasting, relief from the condition.

Paresthesia caused by stroke may receive some temporary benefit from high doses of Baclofen multiple times a day. HIV patients who self-medicate with cannabis report that it reduces their symptoms.

Paresthesia caused by shingles is treated with appropriate antiviral medication.

Because neuroinflammation has been associated with a variety of neurodegenerative diseases, there is increasing interest to determine whether reducing inflammation will reverse neurodegeneration. Inhibiting inflammatory cytokines, such as IL-1β, decreases neuronal loss seen in neurodegenerative diseases. Current treatments for multiple sclerosis include interferon-B, Glatiramer actetate, and Mitoxantrone, which function by reducing or inhibiting T Cell activation, but have the side effect of systemic immunosuppression In Alzheimer's disease, the use of non-steroidal anti-inflammatory drugs decreases the risk of developing the disease. Current treatments for Alzheimer's disease include NSAIDs and glucocorticoids. NSAIDs function by blocking conversion of prostaglandin H2 into other prostaglandins (PGs) and thromboxane (TX). Prostoglandins and thromboxane act as inflammatory mediators and increase microvascular permeability.
