Leukodystrophies are a group of hereditary diseases that are known to cause spastic hemiplegia. Brain infections that cause spastic hemiplegia are meningitis, multiple sclerosis, and encephalitis. [7] The spasticity occurs when the afferent pathways in the brain are compromised and the communication between the brain to the motor fibers is lost ...
The cause of spasticity is thought to be where an imbalance occurs in the excitatory and inhibitory input to α motor neurons caused by damage to the spinal cord and/or central nervous system. The damage causes a change in the balance of signals between the nervous system and the muscles, leading to increased excitability in muscles.
The cause of spasms is often unknown, but it can be due to an inherited genetic problem, a side effect of meds, Parkinson's disease, a stroke, cerebral palsy or multiple sclerosis. [3] Old age can also cause spasms and cramp. [4] Spasms can occur in dystonia, and in spasticity.
Tremor and ataxia are frequent in MS and present in 25 to 60% of patients. They can be very disabling and embarrassing, and are difficult to manage. [139] The origin of tremor in MS is difficult to identify but it can be due to a mixture of different factors such as damage to the cerebellar connections, weakness, spasticity, etc.
Cerebellar tremor (also known as intention tremor) is a slow, broad tremor of the extremities that occurs at the end of a purposeful movement, such as trying to press a button or touching a finger to the tip of one's nose. In classic cerebellar tremor, a lesion on one side of the brain produces a tremor in that same side of the body that ...
Doing the same motion repeatedly can cause muscles, ligaments, and tendons to become swollen and inflamed, which causes the ache. In addition to aches, you may notice a lack of strength and ...
Spasticity, a velocity-dependent change in muscle tone; Clasp-knife response where initial higher resistance to movement is followed by a lesser resistance; Babinski sign is present, where the big toe is raised (extended) rather than curled downwards (flexed) upon appropriate stimulation of the sole of the foot. The presence of the Babinski ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e ...
