While pain is common in people with Guillain–Barré syndrome, studies comparing different types of pain medication are insufficient to make a recommendation as to which should be used.

Plasmapheresis and intravenous immunoglobulins (IVIG) are the two main immunotherapy treatments for GBS. Plasmapheresis attempts to reduce the body's attack on the nervous system by filtering antibodies out of the bloodstream. Similarly, administration of IVIG neutralizes harmful antibodies and inflammation. These two treatments are equally effective, but a combination of the two is not significantly better than either alone. Plasmapheresis speeds recovery when used within four weeks of the onset of symptoms. IVIG works as well as plasmapheresis when started within two weeks of the onset of symptoms, and has fewer complications. IVIG is usually used first because of its ease of administration and safety. Its use is not without risk; occasionally it causes liver inflammation, or in rare cases, kidney failure. Glucocorticoids alone have not been found to be effective in speeding recovery and could potentially delay recovery.

Most patients reported in the literature have been given treatments suitable for autoimmune neurological diseases, such as corticosteroids, plasmapheresis and/or intravenous immunoglobulin, and most have made a good recovery. The condition is too rare for controlled trials to have been undertaken.

Bickerstaff brainstem encephalitis is a rare inflammatory disorder of the central nervous system, first described by Edwin Bickerstaff in 1951. It may also affect the peripheral nervous system, and has features in common with both Miller Fisher syndrome and Guillain–Barré syndrome.

It is expected that there will be no new cases of progressive inflammatory neuropathy since the process of aerosolizing the pig brains has been discontinued at all pork processing facilities.

Supportive treatment is the only intervention for acute cerebellar ataxia of childhood. Symptoms may last as long as 2 or 3 months.

In October 2007 an astute medical interpreter noticed similar neurological symptoms being reported by Spanish-speaking patients seeking treatment from different physicians at the Austin Medical Center, in Austin, Minnesota. Not only did these patients share similar neurological symptoms, they also worked at the same pork processing plant. Dr. Daniel LaChance, a physician at both the Austin Medical Center and the Mayo Clinic in nearby Rochester, Minnesota, was notified. He launched a request to area physicians to refer other patients with similar symptoms to him. The Minnesota Department of Health (MDH) was notified and began an investigation into the "outbreak." The MDH identified workers from two other pork processing plants in Indiana and Nebraska who also had parallel neurological complaints. Several agencies including the Occupational Safety and Health Administration (OSHA) and the Center for Disease Control and Prevention (CDC) were brought in to assist. Simultaneously investigations were conducted to rule out contagious disease, to locate the source or carrier, and to identify what exactly was causing these workers to develop these symptoms.

Removal from exposure was the first line of treatment. Due to progressive sensory loss and weakness, immunotherapy was often required. These treatments included intravenous methylprednisolone, oral prednisone, azathioprine, and/or immunoglobulin. All 24 patients improved, including 7 who received no treatment and 17 who required immunotherapy.

Acute cerebellar ataxia is the most common cause of unsteady gait in children. The condition is rare in children older than ten years of age. Most commonly acute cerebellar ataxia affects children between age 2 and 7 years.

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.

Currently the mechanism of spread and infection is unknown despite the tedious epidemiological, clinical, and neurological studies that have been conducted. Recent Studies show Horizontal Disease Transmission, or the transmission of a disease from one individual to another of the same generation. It appears that VE is an infectious disease; however, the incubation period would have to be very extensive (in excess of 5 years). Many infected individuals attribute the initial symptoms as a result of a plunge in frigid waters. So far, no causative agent has been found in blood, spinal fluid, or brain tissue.

Currently, there is no direct treatment for AEN. Only treatment is for the underlying main diseases or conditions. Appropriate hydration is set. Antacids are also added for further recovery support. Common support drugs of antacids are either H receptor antagonists, and/or a proton pump inhibitor. Sucralfate was used as an option. Parenteral nutrition greatly increased chance of recovery. An esophagectomy can be issued if the disorder is severe enough.

Acute care is the early and specialist management of adult patients suffering from a wide range of medical conditions requiring urgent or emergency care usually within 48 hoursof admission or referral from other specialties.

Acute hospitals are those intended for short-term medical and/or surgical treatment and care. The related medical speciality is acute medicine.

Acute GPP typically requires inpatient management including both topical and systemic therapy, and supportive measures. Systemic glucocorticoid withdrawal is a common causative agent. Withdrawal or administration of certain drugs in the patient's previous medication regimen may be required. Oral retinoids are the most effective treatment, and are considered first line. Cyclosporine or infliximab may be required for particularly acute cases.

Acute esophageal necrosis made an appearance on an American medical drama show, . Jan Garavaglia, the show's host, receives a female body, that at time of the autopsy had a severe case of acute esophageal necrosis due to chronic alcoholism.

Hydroxyurea is a medication that can help to prevent acute chest syndrome. It may cause a low white blood cell count, which can predispose the person to some types of infection.

Research has concluded that VE has been present in the Viuli valley for many centuries among the Evenki populations of northern Siberia. The disease had its debut through its first Iakut diagnosis a little over a century ago in villages of the Viuli region of Siberia. Not until after World War II did the Yakut people become aware of this mysterious killer. The locals and Northern Evenkis referred to this illness as “Bokhoror” or “the stiffness” because of the typical rigidity of the limbs those infected individuals experienced. Viliuisk Encephalomyelitis is currently isolated in the Iakut (Sakha) populations of Siberia, Russia. However, extensive migration might allow the disease to become a continental epidemic as it has already spread the infection radius many miles since its induction in the early 1900s.

Fifty years ago it was believed that the Iakut people had extremely degraded immune systems as result of malnourishment and starvation from the World War. It was believed that this disease was docile and those with healthy immune systems could easily fight it off. This inclination appeared to be accurate until a case of a single Caucasian Russian woman. Supposedly, she infected herself as a means to end her own life. She injected herself with cerebrospinal fluid of a victim of VE, and died as a result of it. This is the first and only reported infection and death of a Caucasian.

Horses that suffer from this disease can never be considered cured, although they can be managed by careful use of the therapy described above, and fast detection of new flare-ups. If the disease is not properly treated, it will eventually lead to blindness.

In medicine, describing a disease as acute denotes that it is of short and, as a corollary of that, of recent . The quantitation of how much time constitutes "short" and "recent" varies by disease and by context, but the core denotation of "acute" is always qualitatively in contrast with "chronic", which denotes long-lasting disease (for example, in acute leukemia and chronic leukemia). In addition, "acute" also often connotes two other meanings: onset and , such as in acute myocardial infarction (EMI), where suddenness and severity are both established aspects of the meaning. It thus often connotes that the condition is fulminant (as in the EMI example), but not always (as in acute rhinitis, which is usually synonymous with the common cold). The one thing that acute MI and acute rhinitis have in common is that they are not chronic. They can happen again (as in recurrent pneumonia, that is, multiple acute pneumonia episodes), but they are not the same ongoing for months or years (unlike chronic obstructive pulmonary disease, which is).

A noncount sense of "acute disease" refers to the acute phase, that is, a short course, of any disease entity. For example, in an article on ulcerative enteritis in poultry, the author says, "in acute disease there may be increased mortality without any obvious signs", referring to the acute form or phase of ulcerative enteritis.

During an acute flare-up, therapy is targeted at reducing the inflammation present, and dilating the pupil. Mydriasis is important, as pupillary constriction is the primary reason for pain. Anti-inflammatory therapy is usually given both systemically, often in the form of flunixin meglumine, and topically, as prednisolone acetate. The mydriatic of choice is atropine. In the periods between acute attacks, no therapy has been shown to be beneficial.

It may result in death, and it is one of the most common causes of death for people with sickle cell anemia.

Treatment of acute proliferative glomerulonephritis consists of blood pressure (BP) control:also a renal biopsy may be needed to be performed at some point. A low-sodium diet may be needed when hypertension is present. In individuals with oliguric acute kidney injury, the amount of potassium should be controlled.

Treatment is primarily supportive. Management in an intensive care unit is required and the need for mechanical ventilation is common. Therapy with corticosteroids is generally attempted, though their usefulness has not been established. The only treatment that has met with success to date is a lung transplant.

It is unclear whether or not acute proliferative glomerulonephritis (i.e., poststreptococcal glomerulonephritis) can be prevented with early prophylactic antibiotic therapy, with some authorities arguing that antibiotics can prevent development of acute proliferative glomerulonephritis, while others reject that antibiotics can prevent acute proliferative glomerulonephritis.

The disorder has been named after Leo Ritter von Zombusch, who first described two cases of a brother and a sister in 1910. The patients experienced patterns of redness and pustule formation over several years, often associated with use of topical medications. Unfortunately one of the two siblings died from complications of the disease.
