Sleep Disorders
|
Narcolepsy, Sleep apnea, Insomnia, Sleep Terror, Sleep Paralysis
|
|
|
Narcolepsy
|
people who suddenly unexpectedly fall asleep. They can have serious head injuries
|
|
|
Sleep Apnea
|
Have problems breathing during sleep. Breathing can stop in the have problems breathing during sleep. Breathing can stop in middle of the night and for a long period of time. Problem carrying oxygen to the brain and parts of the body.
|
|
|
Sleep Terror
|
Happens often in children whose brains are still developing. Semi sleep stage that gets them into a very anxious mode.
|
|
|
Sleep Paralysis
|
Waking up but your body isnt awake.
|
|
|
Sleep Talking
|
May occur during REM or NREM sleep.
|
|
|
Sleepwalking
|
Occurs during NREM sleep; may be difficult to awaken individual.
|
|
|
NERM sleep
|
Consists of four stages of sleep
-NON RAPID EYE MOVEMENT. also known as quiet sleep. |
|
|
REM sleep
|
commonly associated with dreaming.
Muscular acitivity is reduced RAPID EYE MOVEMENT.also known as active or paradoxical sleep |
|
|
Sleep Cycle
Stage 1 |
-Is associated with low-amplitude brain waves; Theta waves.
-slow eye movements -irregular breathing -muscle relaxation individuals awaken easily. |
|
|
Sleep Cycle
Stage 2 |
characterized by sleep spindles and K complex brain wave patterns.
|
|
|
Sleep Cycle
Stage 3 |
Occurs when delta waves are present 20-50% of the time.
-Virtually no eye movement. -'may sleepwalk |
|
|
Sleep Cycle
Stage 4 |
Occurs when delta waves predominate; it is difficult to wake an individual
|
|
|
Sleep
|
characterized by reduced activity and responsiveness and distinctive brain wave patterns.
|
|
|
Stage 1 REM
|
beta waves, low amplitude- high frequency.
-rapid eye movements -no muscular activity -dreaming, easily wakened. |
|
|
If you sleep 8 hours a night, you experience _ complete sleep cycles each night
|
Five.
|
|
|
We tend to have our longest dream period during the ___ part of the night
|
last
|
|
|
Electrical stimulation of the ___ causes animals to fall asleep
|
Raphe System
|
|
|
Raphe System
|
Most active at time of sleep onset
|
|
|
A person who is sleep walking is
|
in stage 3 or stage 4 sleep.
|
|
|
Sleep pills like barbiturates disrupt the ___ portion of sleep cycle by _____ the amount of time spend in this portion
|
REM and stage 4/ decreasing.
|
|
|
The atonia produced during REM sleep
|
Keeps people from phsycially acting out their dreams.
|
|
|
During Sleep brain produces Beta Waves, what are they?
|
Small and fast. Occurs during earliest phases of sleep when you are relatively awake and elert.
|
|
|
Alpha waves occur when the brain begins to .......
|
relax and slow down. during this time when you are not quite asleep, you may experience strange and extremely vivd sensations known as hynagogic hallucinations.
|
|
|
Stage 1
|
Stage 1 is the beginning of the sleep cycle, and is a relatively light stage of sleep. Stage 1 can be considered a transition period between wakefulness and sleep. In Stage 1, the brain produces high amplitude theta waves, which are very slow brain waves. This period of sleep lasts only a brief time (around 5-10 minutes), and if you awaken someone in the stage, they might report that they weren't really asleep
|
|
|
Stage 2
|
Stage 2 is the second stage of sleep and lasts for approximately 20 minutes. The brain begins to produce bursts of rapid, rhythmic brain wave activity known as sleep spindles. Body temperature starts to decrease and heart rate begins to slow.
|
|
|
Stage 3
|
Deep, slow brain waves known as delta waves begin to emerge during stage 3 sleep. Stage 3 is a transitional period between light sleep and a very deep sleep.
|
|
|
Stage 4
|
Stage 4 is sometimes referred to as delta sleep because of the slow brain waves known as delta waves that occur during this time. Stage 4 is a deep sleep that lasts for approximately 30 minutes. Bed-wetting and sleepwalking usually occur at the end of stage 4 sleep.
|
|
|
Stage 5
|
Most dreaming occurs during the fifth stage of sleep, known as rapid eye movement (REM) sleep. REM sleep is characterized by eye movement, increased respiration rate, increased brain activity. REM sleep is also referred to as paradoxical sleep because while the brain and other body systems become more active muscles become more relaxed. Dreaming occurs due because of increased brain activity, but voluntary muscles become paralyzed.
|
|
|
Why do we sleep?
|
1) to conserve energy
2) to avoid predators 3) for restoration 4) for memory |
|
|
Manifest Content
|
what you actually see in a dream
|
|
|
Latent Content
|
the symbol or meaning of the dream
|
|
|
DIssociation Theory
|
when we are hypnotized we operate on more than one level of awareness.
-our behaviors become separated from our awareness |
