Bedwetting

Enuresis, commonly known as bedwetting, is the involuntary release of urine during sleep

Deepest sleep stage

STAGE 3 Non-REM

Nightmares vs Night Terrors

Night terrors are when Sleeper experiences a sense of panic and may scream or attempt to escape that occur during NREM sleep.

-Nightmares are vivid, memorable dreams occurring during REM sleep

Paradoxical sleep

REM sleep is referred to as paradoxical sleep because of combination of high brain activity and lack of muscle tone.

REM Behavior Disorder

a sleep condition where the normal muscle paralysis during REM sleep is absent or incomplete, causing you to physically act out vivid, often violent dreams with movements like punching, kicking, or shouting

REM sleep

REM sleep is rapid movements of the eyes. referred to as paradoxical sleep because of combination of high brain activity and lack of muscle tone.

Slow-wave

STAGE 3 Non-REM

delta waves

low frequency,

high amplitude,

desynchronized.

Stage 1 Non-REM

Transitional phase occurring between wakefulness and sleep.

- Rates of respiration and heartbeat slow down.

- Overall muscle tension and core body temperature decrease.

- Alpha waves

Stage 2 Non-REM

The body goes into deep relaxation.

- Theta waves

- Characterized by the appearance of

both sleep spindles and K-

complexes.

Stage 3 Non-REM

Known as slow-wave sleep.

- Delta waves.

- Respiration and heart rate slow down further.

Stage 4

REM sleep, is the final stage of the sleep cycle

What are sleep sindles what stage does it occur in

stage 2- rapid burst of high

frequency brainwaves.

What are k-complexes and what stage does it occur in

occurs in stage 2 – very high amplitude

pattern of brain activity.
