Q

Alzheimer’s Disease

A

2 abnormal structures in the brain:

  1. Amyloid plaques - clumps of protein fragments that accumulate outside of cells
  2. Neurofibrillary tangles - clumps of altered proteins inside cells (also known as tau tangles)
  • destruction & death of nerve cells that cause memory failure, personality changes, problems carrying out daily activities & other symptoms
  • healthy people also have this but with Alzheimers it is at a faster rate
  • avg duration 8 years
40
Q

Parkinson’s Disease

A

Primarily caused by abnormally low dopamine levels

  • Dopaminergic neurons in substantia nigra of the basal ganglia die off, making it harder to control movements
  • dopamine involved in sending messages to areas of brain that control coordination & movement
  • abnormal aggregates of protein called Lewy body develop inside neurons
41
Q

Sleep-wake disorders

A

Disturbance in quality, amount and timing of sleep

42
Q

Specific Diagnoses of Sleep-Wake Disorders

A

Dyssomnias: abnormalities in the amount, quality or timing of sleep

  1. Insomnia - inability to fall or remain asleep
  2. Narcolepsy - periodic, overwhelming sleepiness during waking periods
  3. Sleep apnea - intermittent cessation of breathing during sleep, which results in repeated awakenings

Parasomnias: abnormal behaviours that occur during sleep

  1. Somnambulism: sleep walking
    - tends to occur during slow wave sleep (stage 3)
    - usually happens during the first third of the night
    - many children experience sleep-walking and eventually grow out of it
  2. Night terrors: appearing terrified, babbling, screaming while deep asleep
    - usually occur during stage 3 (unlike nightmares which happening during REM)

Q

Tolerance

A

Occurs when an individual must use more of a drug to achieve the desired effect

46
Q

Dependence

A

Develops when a person needs to use a drug in order to function normally

47
Q

Withdrawal

A

Describes the group of symptoms that occur when a person who has formed a dependance to a drug suddenly discontinues or decreases use of that drug
- symptoms are drug-specific & dose dependent

48
Q

49
Q

Psychological Dependence vs Physical Dependence

A

Psychological

  • occurs when drug becomes central to person’s thoughts, emotions & activities
  • demonstrated by strong urge to use drug, despite being aware of its harmful effects
  • not all drugs lead to physical dependence, it’s possible for any drug to lead to psych dependence

Physical

  • demonstrated by presence of withdrawal symptoms when drug is not consumed
  • person depends on drug to avoid withdrawal symptoms & to fx normally
  • often follows heavy daily use over several weeks or longer
50
Q

Psychoactive drugs

A

Work by altering actions at neuronal synapse

- enhance, suppress or mimic activity of neurotransmitter

51
Q

Drug Classes & Effects

A

Depressants
Examples: alcohol, barbiturates, opiates
Action: Depresses CNS (Esp F/F)
Effect: impaired motor control, organ failure from overose

Stimulants
Examples: caffeine, nicotine, amphetamines, cocaine
Action: Increases availability & action of neurotransmitters
Effect: Sympathetic activation; rush or high followed by a crash

Hallucinogens
Examples: THC, Marijuana, LSD
Action: Distorts perception
Effect: Hallucinations, impaired judgement, slowed rx time

52
Q

Consciousness

A

Awareness we have of ourselves, our internal state & environment

  • imp for reflection & directs our attn
  • needed to complete novel & complex tasks but little awareness for practiced & simple tasks
53
Q

States of consciousness

A

Alert

Sleep

54
Q

RAS

A

Reticular activating system

  • controls alertness & arousal
  • is a network of nerve pathways in brain stem that connects spinal cord, cerebrum & cerebellum
  • mediates overall level of consciousness
55
Q

Electroencephelograph

A

Documents different wave lengths

56
Q

Waves, frequencies & characteristics

A

Alpha - 7 to 14 Hz
- associated with relaxed normal consciousness

Beta - 15 to 30 Hz
- higher frequency than alpha, more alert consciousness

Theta - 4 to 7 Hz
- seen in young children, meditative states & stages 1 sleep

Delta - Less than 4 Hz
- occurs during slow wave sleep

57
Q

Circadian rhythm

A

Controls increases & decreases in alertness in predictable ways over 24-h cycle

12 am - 6 am –> sleep
6 am - 10 pm –> slow increase in sleep need
10 pm - 12 am –> sleep

12 am - 12 pm –>sleep urge decreases
After 12 pm & 8 pm sleep urge increases

58
Q

3 physiological indicators of mammal’s circadian rhythm

A
  1. Melatonin levels released by pineal gland (during day it is inactive)
  2. Body temperature controlled by hypothalamus (36-38 degrees celsius)
  3. Cortisol controlled by adrenal cortex
59
Q

Suprachiasmatic Nucleus (SCN)

A
  • found in hypothalamus
  • controls sleep, melatoin production & body temp
  • cortisol release is controlled by multiple things, only one is SCN
60
Q

Sleep Stages

A

Stage 1 (theta waves)
EDG- slow rolling eye movements
EMG- moderate body activity
Characteristics - fleeting thoughts, non-REM sleep

Stage 2 (sleep spindle, K-complex)
EDG- no eye movement
EMG- moderate body activity
Characteristics - increased relaxation, decreased temp, heart rate & respiration

Stage 3 & 4 (delta waves)
EDG- no eye movement
EMG- moderate body activity
Characteristics - heart & digestion slow, growth hormones secreted, deepest level of sleep

REM (similar to beta waves but more jagged; low intensity, high frequency)
EDG- bursts of quick eye movements
EMG- almost no body activity (paradoxical sleep bc no body activity but brain is active)
Characteristics - when dreams occur

61
Q

Hypnosis

A

Attention is more focused and peripheral awareness is reduced

  • more low frequency > high frequency
  • decrease in left hemisphere activity & increase in right hemisphere activity
62
Q

Meditation

A

Practice in which individual induces mode of consciousness for some purpose

  • effective for stress reduction
  • increases activity in left frontal lobe (area active in most optimistic people)
  • improved concentration, lowered bp, & better immune fx
  • lower frequency alpha & theta waves
  • if meditated for a long time, lots of brain areas appear to be altered esp in left hemisphere
63
