Image sourced and used with permission from Centre for Neuro Skills. The vestibular system in each inner ear is made up of three semi-circular canals and two pockets, called the otolith organs, which together provide constant feedback to the cerebellum about head movement. Symptom management Spasticity or fatigue may indirectly affect balance.
These conditions can be managed with medications in addition to physical and occupational therapy. The simple loss of coordination ataxia or mobility can be one of the most frustrating aspects of multiple sclerosis MS. Ataxia is incoordination caused by dysfunction to sensory nerve inputs, motor nerve outputs, or the processing of them.
It's not the result of muscular weakness. Ataxia is most often applied to unsteadiness in walking but it also refers to upper body incoordination and dysfunction in eye movements and speech. Ataxia is common in MS but is also seen in several other conditions including diabetic polyneuropathy, acute transverse myelitis, vacuolar myelopathy, tumor or cord compression and hereditary forms of ataxia. Cerebellar Ataxia Cerebellar ataxia indicates ataxia due to dysfunction of the cerebellum.
This is caused by lesions in the cerebellum or in the parts of the brain that connect to it, such as the cerebellar peduncles, the pons or the red nucleus. This causes a variety of elementary neurological deficits, such as antagonist hypotonia, asynergy, dysmetria, dyschronometria, and dysdiadochokinesia. How and where these abnormalities manifest depend on which cerebellar structures are lesioned, and whether the lesion is bilateral or unilateral.
Because the cerebellum is responsible for synchronizing voluntary muscle movement throughout the body, this can cause movement to become out-of-sync. Dysmetria - Reduced control of range of movement such as over or under-shooting targets. Balance and Vertigo. Gait and balance disturbances are common with MS. Stroke is a clot or bleed in any part of the brain.
The cerebellum is a less common site for stroke than the cerebrum, but it can still occur there. A clot or bleed in the cerebellum can cause the following:. Treating the stroke might resolve the ataxia. Occupational and physical therapy can help manage any permanent damage.
Tumors are abnormal cells that can either grow in the brain or migrate there from a different part of the body. These tumors might be benign and not spread through the body.
Malignant tumors grow and spread, leading to cancer. Diagnosis and treatment will vary based on age, the overall state of health, the course of the disease, the potential outlook, and other factors. Reducing the risk of stroke, brain injury, and exposure to poisons can help prevent some forms of ataxia.
