Parkinson's disease (characterized by tremors and progressive rigidity of limbs) is caused by degeneration of brain neurons that are involved in movement control and make use of neurotransmitter
acetylcholine
norepinephrine
dopamine
GABA
C.
dopamine
A dopamine deficiency is due to low level of dopamine in the body. It leads to a problem with the receptors in the brain and develops into Parkinson's disease or depression.
Acetylcholine is a major neurotransmitter responsible for memory and learning. It can lead to diseases such as dementia and Alzheimer's.
Norepinephrine promotes arousal and alertness. Increased levels of norepinephrine leads to excessive activity of sympathetic nervous system, and it can further lead to obesity, metabolic syndrome and high blood pressure.
GABA or Gamma- Amino Butyric Acid deficiency can lead to depression, anxiety, insomnia etc.
