Acute Cerebellar Ataxia Overview
Learn About Acute Cerebellar Ataxia
View Main Condition: Movement Disorders
Acute cerebellar ataxia is the sudden inability to coordinate muscle movement due to disease or injury to the cerebellum. This is the area in the brain that controls muscle movement. Ataxia means loss of muscle coordination, especially of the hands and legs.
Cerebellar ataxia; Ataxia - acute cerebellar; Cerebellitis; Post-varicella acute cerebellar ataxia; PVACA
Acute cerebellar ataxia in children, particularly younger than age 3, may occur several days or weeks after an illness caused by a virus.
Viral infections that may cause this include chickenpox, Coxsackie disease, Epstein-Barr, echovirus, among others.
Other causes of acute cerebellar ataxia include:
- Abscess of the cerebellum
- Alcohol, medicines, insecticides, and illicit drugs
- Bleeding into the cerebellum
- Multiple sclerosis
- Strokes of the cerebellum
- Vaccination
- Trauma to head and neck
- Certain conditions associated with some cancers (paraneoplastic disorders)
Ataxia may affect movement of the middle part of the body from the neck to the hip area (the trunk) or the arms and legs (limbs).
When the person is sitting, the body may move side-to-side, back-to-front, or both. Then the body quickly moves back to a sitting upright position.
When a person with ataxia of the arms reaches for an object, the hand may sway back and forth.
Common symptoms of ataxia include:
- Clumsy speech pattern (dysarthria)
- Repetitive eye movements (nystagmus)
- Uncoordinated eye movements
- Walking problems (unsteady gait) that can lead to falls
- Difficulty controlling arm movements
Treatment depends on the cause:
- If the acute cerebellar ataxia is due to bleeding, surgery may be needed.
- For an ischemic stroke, medicine to thin the blood can be given. Removing a blood clot from within the blood vessels may also be needed.
- Infections may need to be treated with antibiotics or antivirals.
- Corticosteroids may be needed for swelling (inflammation) of the cerebellum (such as from multiple sclerosis).
- Cerebellar ataxia caused by a recent viral infection may not need treatment.
- Physical therapy may be needed to reduce risk of falling.

People whose condition was caused by a recent viral infection should make a full recovery without treatment in a few months. Strokes, bleeding, or infections may cause permanent symptoms.
Falls may result in injury.
In rare cases, movement or behavioral disorders may persist.
Contact your provider if any symptoms of ataxia appear.
Summary: This study is being carried out at Multiple Sclerosis (MS) centers to evaluate whether a full-body stimulation suit at home can help people with Multiple Sclerosis (pwMS) reduce symptoms like spasticity (muscle stiffness) and ataxia (poor coordination), and improve daily functioning. Can pwMS who experience spasticity or ataxia benefit from using a stimulation suit for 6 weeks? Researchers will co...
Summary: Cerebellar ataxias are a group of rare neurological disorders that are clinically and genetically heterogeneous, with several hundred genes and diseases known to date. Over the last decade, their diagnosis has been revolutionised by the development of high-throughput sequencing technologies such as exome/genome sequencing (ES/GS), making it possible to obtain a molecular diagnosis in a growing num...
