Parkinson’s disease

A disease characterized as a progressive motor disability manifested by tremors, shaking, muscular rigidity, and lack of postural reflexes.

A progressive degenerative disorder of the central nervous system characterized by loss of dopamine producing neurons in the substantia nigra and the presence of lewy bodies in the substantia nigra and locus coeruleus. Signs and symptoms include tremor which is most pronounced during rest, muscle rigidity, slowing of the voluntary movements, a tendency to fall back, and a mask-like facial expression.

A progressive disorder of the nervous system marked by muscle tremors, muscle rigidity, decreased mobility, stooped posture, slow voluntary movements, and a mask-like facial expression.

A progressive, degenerative neurologic disease characterized by a tremor that is maximal at rest, retropulsion i.e. A tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. Lewy bodies are present in the substantia nigra and locus coeruleus but may also be found in a related condition lewy body disease, diffuse) characterized by dementia in combination with varying degrees of parkinsonism.

Parkinson’s disease is a disorder that affects nerve cells, or neurons, in a part of the brain that controls muscle movement. In parkinson’s, neurons that make a chemical called dopamine die or do not work properly. Dopamine normally sends signals that help coordinate your movements. No one knows what damages these cells. Symptoms of parkinson’s disease may include

Progressive, degenerative disorder of the nervous system characterized by tremors, rigidity, bradykinesia, postural instability, and gait abnormalities; caused by a loss of neurons and a decrease of dopamine in the basal ganglia.

Major neurocognitive disorder in other diseases classified elsewhere unspecified severity, with anxiety
