Module 3 - Alcohol, Red drugs, and Mental Health Flashcards
T/F: The brain undergoes an intense period of development between the ages of 13 and 19.
False: 16 and 25
T/F: The central nervous system comprises the brain and the spinal cord.
True
List the four components of a neuron
- Dendrites
- Acon
- Myelin sheath
- Synapse
T/F: The brain is divided into four lobes = the frontal lobe, the parental lobe, temporary lobe, and occipital lobe
False: frontal, PARIETAL, TEMPORAL, and occipital
What is the frontal lobe responsible for?
Frontal: high level cognitive functions and control the voluntary movement
What are grey matter and white matter?
Grey: mostly found in the cortex (outermost region of cerebrum) of the brain: contains neuronal cell bodies and synapses.
White: found under the cortex and within cerebrum (large upper part of brain): contains myelinated axons.
T/F: amount of white matter decreases with age and the amount of white matter also decreases.
False: grey decreases, white increases
List three main changes in the brain during early adulthood.
- Increased synaptic pruning (extra neurons and synaptic connections are eliminated to increase efficiency)
- Increased myelination
- Improved connectivity (larger more widely distributed neural networks)
What’s the difference between substance use and substance misuse?
Use: refers to use of psychoactive substance (caffeine, alcohol, cannabis, other illicit drugs)
Misuse: use of psychoactive substance that causes concern or elevates risk of reduced well-being/poor mental health. Included regular/excessive use, medication for purpose other than perscribed, binge-drinking
What is the difference between substance use and substance use disorder?
Substance use disorder: clinically significant abuse or dependency which includes psychological and physiological aspects of an addiction. The more diagnostic criteria a person has, the more severe the disorder.
What are some effects of substance use during adolescence?
- Mental health problems (poor sleep, anxiety, depression, psychosis)
- Altered efficiency of brain functions
- Reduced sustained attention/distraction/errors
- Poorer university performance
- Low drive + low motivation
Define “disinhibition”
Lowering of one’s inhibitions
Binge-drinking is defined as +__ drinks for females and +__ drinks for males at a single period
4, 5
What are some -ve outcomes of binge drinking?
- risk of physical harm
- blackouts
- hangovers
- poor academic performance
T/F: On average, your liver can metabolize 1 oz of alcohol every hour (equiv. 2/3 of a st. size shot)
True
