Parkinson's Disease causes constipation and gastric dysmotility that is severe enough to endanger comfort and even health. [26] A factor in this is the appearance of Lewy bodies and Lewy neurites even before these affect the functioning of the substantia nigra in the neurons in the enteric nervous system that control gut functions.
Neuropsychiatric symptoms like anxiety, apathy, depression, hallucinations, and impulse control disorders occur in up to 60% of those with Parkinson's. They often precede motor symptoms and vary with disease progression. [34] Non-motor fluctuations, including dysphoria, fatigue, and slowness of thought, are also common. [35]
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.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Paralysis is most often caused by damage in the nervous system, especially the spinal cord.Other major causes are stroke, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson's disease, ALS, botulism, spina bifida, multiple sclerosis, and Guillain–Barré syndrome.
In children, the most common cause is a stroke of the ventral pons. [9]Unlike persistent vegetative state, in which the upper portions of the brain are damaged and the lower portions are spared, locked-in syndrome is essentially the opposite, caused by damage to specific portions of the lower brain and brainstem, with no damage to the upper brain.
The clinical symptoms are strikingly similar to those of Neurolathyrism. They are also similar to those of viral tropical spastic paraparesis and hereditary spastic paraparesis, but those two disorders have a slow onset. Konzo is clinically distinct from polio which is a flaccid paralysis and which most often affects a person asymmetrically.
Since bubbles can form in or migrate to any part of the body, DCS can produce many symptoms, and its effects may vary from joint pain and rashes to paralysis and death. DCS often causes air bubbles to settle in major joints like knees or elbows, causing individuals to bend over in excruciating pain, hence its common name, the bends.
A condition which affects the muscles necessary for speech, it causes difficulty in speech production despite a continued cognitive understanding of language. Often caused by Parkinson's disease, patients experience weakness, paralysis, or lack of coordination in the motor-speech system, causing respiration , phonation , prosody , and ...
