Identify how abnormal levels of specific neurotransmitters may be involved in each of these disorders: Alzheimer's disease, Parkinson's disease, and schizophrenia.
What will be an ideal response?
Students' examples may vary.
The answer should contain the following information:
Alzheimer's disease may be associated with diminished production of the neurotransmitter acetylcholine (ACh). Acetylcholine is found throughout the nervous system. It transmits messages relating to skeletal muscles and is involved in memory capabilities.
Parkinson's disease is caused by a deficiency of the neurotransmitter dopamine in the brain. Dopamine is involved in movement, attention, and learning.
On the other hand, schizophrenia is hypothesized to be affected or caused by unusually high levels of dopamine. Drugs that block the reception of dopamine reduce the symptoms displayed by some people diagnosed with schizophrenia.
