Children with childhood dementias suffer severe sleep disturbances, movement disorders (e.g. muscle spasms, tremors), deterioration of communication skills, loss of vision and hearing, mood disorders, psychosis (including hallucinations and delusions) and incontinence. [3] This situation can cause many emotional changes for parents and children.
[6] [4] Light seems to have therapeutic antidepressant effects when an organism is exposed to it at appropriate times during the circadian rhythm, regulating the sleep-wake cycle. [ 6 ] [ 4 ] In addition to mood, learning and memory become impaired when the circadian system shifts due to light stimuli, [ 6 ] [ 20 ] which can be seen in studies ...
The basic rest–activity cycle (BRAC) is a physiological arousal mechanism in humans proposed by Nathaniel Kleitman, [1] hypothesized to occur during both sleep and wakefulness. Empirically, it is an ultradian rhythm of approximately 90 minutes (80–120 minutes [ 2 ] ) characterized by different levels of excitement and rest.
Free-running organisms that normally have one or two consolidated sleep episodes will still have them when in an environment shielded from external cues, but the rhythm is not entrained to the 24-hour light–dark cycle in nature. The sleep–wake rhythm may, in these circumstances, become out of phase with other circadian or ultradian rhythms ...
Benefits include improved thinking or cognition for children ages 6-13, short-term reduction of anxiety for adults, and enhanced functional capacity in older adults. [8] Regular physical activity can keep thinking, learning, and judgment skills sharp with age. It can also reduce the risk of depression and anxiety and improve sleep. [9]
Running can improve mental alertness and sleep. [69] Both research and clinical experience have shown that exercise can be a treatment for serious depression and anxiety even some physicians prescribe exercise to most of their patients. [70] Running can have a longer-lasting effect than anti-depressants. [71]

Sample hypnogram showing one sleep cycle (the first of the night) from NREM through REM. The sleep cycle is an oscillation between the slow-wave and REM (paradoxical) phases of sleep. It is sometimes called the ultradian sleep cycle, sleep–dream cycle, or REM-NREM cycle, to distinguish it from the circadian alternation between sleep and ...
