Death of neurons

WebMotor neuron loss continues until the ability to eat, speak, move, and finally the ability to breathe is lost [2] with the cause of early death usually being respiratory failure. [14] Most cases of ALS (about 90% to 95%) have no known cause, and are known as sporadic ALS. WebParkinson's disease is a neurodegenerative disease caused by the death of neurons, ie, cells critical to the production of dopamine, an important neurotransmitter in the brain. Here, we present a brief review of the dopamine synthetic pathway, binding to the dopamine receptors, and subsequent action.
