neurons do not reproduce
Neural stem cells produce neurons. These cells are found in the central nervous system and have the ability to differentiate into different types of neurons.
While Alzheimer's disease is the most common type of dementia, there are also many other forms, including vascular and mixed dementia. Causes of dementia are mainly produced by inflammation, disease or injury. On such events neurons may die and dementia is the result. Now, scientists believe that a combination of hereditary, environmental, lifestyle are mostly at work. The more neurons die, more intense will be the symptoms of dementia. This disease is currently being researched allover the world, and may be that within the next 10 years it will be conducted to a satisfactory solution.
The nervous system can't transmit messages without neurotransmitters. A person will die if his neurons fail to produce them.

Motor neurons are considered efferent neurons, which means they transmit signals from the central nervous system to the muscles or glands to produce a response. They are responsible for initiating and controlling muscle contractions and movements.
There are three major classes of neurons: sensory neurons, which receive information from the external environment; interneurons, which process and integrate this information; and motor neurons, which send signals to muscles and glands to produce a response.
