Alzheimer's Disease and Dementia Medications

What are the two neurotransmitters targeted by medications for Alzheimer's disease?

• Acetylcholine and glutamate

• Dopamine and serotonin

• GABA and norepinephrine

• Endorphins and oxytocin

What is the role of acetylcholine in the brain?

• It helps neurons communicate

• It breaks down acetylcholinesterase

• It stimulates glutamate receptors

• It regulates dopamine levels

How do cholinesterase inhibitors work in Alzheimer's disease?

• They inhibit the breakdown of acetylcholine

• They increase the production of acetylcholinesterase

• They block glutamate receptors

• They decrease the levels of acetylcholine

What are the side effects of cholinesterase inhibitors?

• Nausea, vomiting, and loss of appetite

• Headache, confusion, and dizziness

• Agitation, irritability, and aggression

• Memory loss, confusion, and anxiety

What neurotransmitter is targeted by memantine?

• Glutamate

• Acetylcholine

• Dopamine

• Serotonin

What is excitotoxicity?

• Cell death due to excessive stimulation

• Memory loss and confusion

• Decreased levels of acetylcholine

• Increased production of glutamate

How does memantine work in Alzheimer's disease?

• It blocks the NMDA receptor for glutamate

• It increases the levels of acetylcholine

• It inhibits acetylcholinesterase

• It stimulates dopamine production

What are the side effects of memantine?

• Headache, confusion, and dizziness

• Nausea, vomiting, and loss of appetite

• Agitation, irritability, and aggression

• Memory loss, confusion, and anxiety

What are the common symptoms of Alzheimer's disease?

• Memory loss, confusion, and difficulty completing familiar tasks

• Increased energy, euphoria, and decreased need for sleep

• Weight gain, increased appetite, and excessive sleepiness

• None of the above

What is the function of NMDA receptors in the brain?

• They regulate the release of dopamine

• They are involved in synaptic plasticity and memory function

• They break down acetylcholine

• They stimulate the production of serotonin
