Question

what kind of neurons are affected by Parkinson's diseases?

Answer 1

ANSWER :- Dopaminergic or dopamine producing neuron

Parkinson's disease (PD) is a progressive disorder that affect nerve cells in the brain responsible for body movement. When dopamine producing neurons die, symptoms such as tremor, slowness, stiffness, and balance problem occur.

Nerve cells or neurons, are responsible for sending and receiving impulses or messages between the body and the brain. Neurons have a cell body with branching arms, called dendrites, which act like antennae and pick up messages. Axons carry messages away from the cell body. Impulses travel from neuron to neuron, from the axon of one cell to the dendrites of another, by crossing over a tiny gap between the two nerve cells called a synapses. Chemical messengers called neurotransmitter allow the electrical impulses to cross the gap.

Parkinson's disease (PD) is a degenerative, progressive disorder that affects the nerve cells in deep part of the brain called the basal ganglia and the substantia nigra. Nerve cells in the substantia nigra produce the neurotransmitter dopamine and are responsible for relaying messages that plan and control body movement. The reason may be that, the dopamine-producing nerve cells of the substantia nigra begin to die off in some individuals. When 80% of dopamine is lost, PD symptoms such as tremor, slowness of movement, stiffness, and balance problem occur .
