Q

Difference between PNS and SNS

A

Para: rest and digest
Symp: FFF

18
Q

The 4 groups of neurotransmitters

A

Cholinergics, Monoamines, amino acids, neuropeptides

19
Q

Cholinergic: Acetylcholine

A

Decreased levels: Alzheimer’s, Huntington’s, Parkinson’s
Decrease: Depression
Help with sleep and memory retention

20
Q

Monoamines: Norepinephrine

A

Decreased levels: Depression
Increased: Mania, Anxiety states, schizophrenia

21
Q

Monamines: Dopamine

A

Decreased Levels: Parkinson’s disease, depression, Tourette syndrome, and ADHD

22
Q

Monamines: Histamine

A

Decreased: depression

23
Q

Amino Acids: GABA

A

Decreased: Huntington’s disease, anxiety disorders, schizophrenia, and various forms of epilepsy

24
Q

Neuropeptides: Substance P

A

Decreased levels: Huntington’s disease and Alzheimer’s disease
Increased levels: Depression
Used for PTSD patients`

25
Q

Neuropeptides: Endorphins and enkephalins

A

Modulation of dopamine activity by opioid peptides may indicate some link to the symptoms of schizophrenia

26
Q

Neuropeptides: Somatostatin

A

Decreased levels: Alzheimer’s disease
Increased levels: Huntington’s disease

27
Q

Hormones of the neuroendocrine system

A

Issues with hormones can greatly affect mental states

28
Q

Antidiuretic Hormone (ADH)

A

Help to maintain our BP & conserve water.
Emotional stress is involved. Polydipsia (drinking a lot). Bipolar and schizophrenia pts have a problem with their ADH.
Location of origin: Posterior lobe of pituitary gland.

29
Q

Oxytocin

A

Location: posterior pituitary lobe
May play a role in stress response by stimulation of ACTH

30
Q

Growth Hormone (GH)

A

anterior pituitary
altered secretion may correlate with anorexia nervosa

31
Q

Thyroid-stimulating hormone (TSH)

A

Decreased: Insomnia, anxiety, emotional lability
Increased: Fatigue, depression
Decreased levels of TSH result in increased thyroid hormones
Anterior pituatary

32
Q

Prolactin

A

Anterior pituitary
Increased: Depression, anxiety , decreased libido, irritability

33
Q

Gonadotropic hormones

A

Anterior P
Decreased: Depression and anorexia nervosa
Increased testosterone: Increased sexual behavior and aggressiveness

34
Q

Melanocyte stimulating Hormone

A

Anterior P
Increased: depression

35
Q

Pituitary gland

A

Circadian rhythms follow a 24 hour cycle and may influence a variety of regulatory functions

36
Q

Genetics
Phenotype vs. Genotype

A

Phenotype: Expressed genes
Genotype: Persons entire set of genes including unexpressed ones.

37
Q

Involvement of Genes vs. environment in the development of mental illness

A

Psychiatric disorders are most likely due to a combination of Genetics and environmental influence
