AP Psych Neurotransmitters

Disorder linked to excess dopamine

Schizophrenia

Disorder linked to deficient dopamine

Parkinson's disease

Condition linked to deficient serotonin

Depression

Mood effect caused by deficient norepinephrine

Depressed mood

Three symptoms linked to deficient GABA

Seizures, tremors, and insomnia

Two symptoms produced by excess glutamate

Migraines and seizures

Condition resulting from an excess of substance P

Chronic pain

Neurotransmitter-producing neurons that deteriorate in Alzheimer's disease

Acetylcholine (ACh)-producing neurons

Effect of excess opioid drugs on natural endorphins

Suppresses the body's natural endorphin supply

Two neurotransmitter deficiencies linked to depressed mood

Serotonin and norepinephrine

Neurotransmitter excess linked to schizophrenia with hallucinations

Excess dopamine

Neurotransmitter imbalance in Parkinson's disease causing tremors and reduced mobility

Deficient dopamine

Neurotransmitter shortage associated with slower movements in Parkinson's disease

Dopamine deficiency

Neurotransmitter deficiency linked to depressive symptoms with disrupted hunger and sleep

Low serotonin

Transmitter deficiency linked to depressed mood and reduced alertness

Low norepinephrine

Neurotransmitter imbalance indicated by seizures, tremors, and insomnia

Deficient GABA

Deficient inhibitory neurotransmitter linked to seizures

GABA

Neurotransmitter whose excess causes migraines through neural overexcitation

Glutamate

Major excitatory neurotransmitter whose excess overstimulates the brain, causing seizures

Excess glutamate

Neurotransmitter whose excessive signaling produces chronic pain

Excess substance P

Neurotransmitter whose surplus is linked to chronic pain

Substance P

Type of neurons that deteriorate in a person with Alzheimer's disease

Acetylcholine (ACh)-producing neurons

Neurotransmitter system involved in Alzheimer's-related memory deficits

Acetylcholine (ACh)

Neurotransmitter found in excess in individuals with schizophrenia

Dopamine

Type of dopamine imbalance associated with Parkinson's disease (excess vs. deficiency)

Too little dopamine (deficiency)

Type of serotonin imbalance associated with depression (excess vs. deficiency)

Too little serotonin (deficiency)

GABA imbalance suggested by insomnia and seizures (excess vs. deficiency)

GABA deficiency

Glutamate imbalance suggested by migraines (excess vs. deficiency)

Glutamate excess

Substance P imbalance suggested by chronic pain (excess vs. deficiency)

Substance P excess

Imbalances distinguishing tremors with slow movement vs. tremors with insomnia

Low dopamine vs. low GABA

Imbalances distinguishing seizures from low inhibition vs. excess excitation

Low GABA vs. high glutamate

Distinction between low-mood symptoms for serotonin vs. norepinephrine deficiency

Serotonin affects sleep and hunger; norepinephrine affects alertness and arousal

Neurotransmitter issues distinguishing Alzheimer's disease vs. Parkinson's disease

Acetylcholine (ACh) neuron deterioration vs. low dopamine

Specific disorder linked to serotonin excess according to Myers' psychology table

No specific disorder listed; it primarily links serotonin undersupply to depression

Cause of natural endorphin suppression (excess natural endorphins vs. excess opioid drugs)

Excess opioid drugs
