Motor System Disorders

Motor system disorders refer to conditions that affect the functioning of the nervous system, leading to difficulties with movement control. These disorders involve dysfunction in the motor pathways, which include the brain, spinal cord, and peripheral nervous system. The motor system is responsible for voluntary and involuntary movements, and motor system disorders can cause symptoms ranging from tremors and rigidity to paralysis and weakness.

 Tremors (resting tremor)

Bradykinesia (slowness of movement)

Muscle rigidity (stiffness)

Postural instability (balance problems)

Gait changes (shuffling walk, difficulty turning

Genetic Mutations: Disorders like Huntington’s disease and certain types of dystonia are caused by inherited mutations.

Neurodegeneration: Conditions like Parkinson's disease, ALS, and multiple sclerosis involve progressive damage to the nervous system.

Trauma: Spinal cord injuries, brain injuries, and physical trauma can cause motor deficits.

Autoimmune Diseases: Diseases like multiple sclerosis and myasthenia gravis involve immune system attacks on the nervous system.
