Cerebellar degeneration is deterioration (damage or death) of the nerve cells in your cerebellum. Your cerebellum is in the back part of your brain. It controls many important functions. These include coordination in balance, standing, walking, speech and muscle movements.
Cerebellum brain damage often occurs due to anoxic brain injury, neurodegenerative disorders, or infection. Alcohol abuse can also cause the cerebellum to deteriorate. When the cerebellum sustains damage, the signals it sends throughout the body become weaker or can cease entirely.
Ataxia usually results from damage to the part of the brain called the cerebellum or its connections. The cerebellum controls muscle coordination. Many conditions can cause ataxia, including genetic conditions, stroke, tumors, multiple sclerosis, degenerative diseases and alcohol misuse.
Cerebellar degeneration is a type of damage to the cerebellum, which is the area of the brain that controls balance and coordination. Cerebellar degeneration is not common. It can occur due to progressive neurological diseases or brain damage, such as a stroke.
Cerebellar dysfunction causes balance problems and gait disorders along with difficulties in coordination, resulting in ataxia, uncoordinated movements, imbalance, dysarthria, nystagmus, and vertigo as a part of the vestibulocerebellar system.
If the cerebellum is damaged, it can result in issues like uncoordinated movement, tremors, or muscle spasms. Damage to this part of the brain is most often caused by a head injury or...
Cerebellar degeneration is a process in which neurons (nerve cells) in the cerebellum—the area of the brain that controls coordination and balance—deteriorate and die. Diseases that cause cerebellar degeneration also can involve the spinal cord and other areas of the brain.
Damage to your cerebellum can interfere with judging the size of or distance from objects. It can also affect your sense of timing. As an example, people with damage to their cerebellum may have trouble repeatedly tapping their fingers, causing them to tap too soon or too late from beat-to-beat.
Damage to the cerebellum can lead to: 1) loss of coordination of motor movement (asynergia), 2) the inability to judge distance and when to stop (dysmetria), 3) the inability to perform rapid alternating movements (adiadochokinesia), 4) movement tremors (intention tremor), 5) staggering, wide based walking (ataxic gait), 6) tendency toward falli...
Treatment. Cerebellar disorders have numerous causes, including congenital malformations, hereditary ataxias, and acquired conditions. Symptoms vary with the cause but typically include ataxia (impaired muscle coordination). Diagnosis is clinical and often by imaging and sometimes genetic testing.
