Narcolepsy usually begins in adolescence or early adulthood, and continues through the personâs life. It is thought that 1 in 2000 people suffer from narcolepsy but it is difficult to get an accurate measure of incidence as some people only have mild symptoms or just donât go to their doctors. Sufferers experience sudden and uncontrollable attacks of sleep at irregular and unexpected times. The two main symptoms are feeling sleepy a lot of the time, and losses of muscular control, episodes triggered by emotional arousal such as anger, fear, amusement, stress or anxiety. Other symptoms can include hallucinations and sleep paralysis - both experienced either when falling asleep or when waking up, and frequent waking up when asleep at night.
Sleep normally occurs in several stages: dreamless periods of light and deep sleep and some periods of active dreaming (REM). This cycle is repeated during the night. AS aging happens most people find it more difficult to fall asleep and stay asleep. Total sleep time may remain or is slightly decreased (6.5 to 7 hours per night). The transition between sleep and wake may be abrupt, giving older people a feeling of being more of a “light sleeper” than they were previously (nih.gov).
Stages 3: This is the deep sleep stage. It's harder to rouse you during this stage, and if someone woke you up, you would feel disoriented for a few minutes. Then comes REM sleep, where your heart rate and breathing quickens and as your brain is more active most of your intense dreams take place during this stage. The amount of time we spend each day sleeping declines throughout our lifetime. As humans grow from infancy to old age there are major changes in the amount and kind of sleep experienced.
Sleepwalking Introduction Sleepwalking, also known as somnambulism, is a behavior disorder that originates during deep sleep and results in walking or performing other complex behaviors while asleep.It is a parasomnia. A parasomnia refers to all the abnormal things that can happen to people when they sleep. In childhood, sleepwalking has prevalence up to 17%, peaking between 8 and 12 years of age, with a strong genetic factor in 65% of cases.At least 20% of the children will experience sleepwalking at least once in their life. Eventually the children will outgrow it in their teens, or sometimes will still persist into adult life. In other cases, adults will sleepwalk too due to certain factors which will be discussed later.
State of Consciousness: Sleep Deprivation Circadian rhythm is a regular biological rhythm with a period of approximately 24 hours and is fundamental adaptation. Circadian rhythm is associated with sleep deprivation because of many different factors. When circadian rhythms are disturbed it throws off our biological clocks and hormones, body temperatures, and digestive cycles. When you lose at least an hour of sleep every night, week after week and month after month it makes it more difficult for a person to pay attention and to remember things. It also causes the reaction time to slow down, sometimes behavior becomes unpredictable, ability to make decisions decline.
The Five Stages Of Sleep Stage one: when you close your eyes, your body temperature drops and brainwaves become slower. You start to nod off, falling into a light sleep when stress hormones start to drop. Stage two: you've lost consciousness, your digestion slows down and functions like hearing are put on standby. Stage three: the first phase of deep sleep, which usually occurs within 15 minutes of falling asleep. Your muscles relax, your blood pressure and heart rate fall and your brain produces slow waves.
What is Sleep Apnea Sleep apnea is a common sleep disorder in which you have one or more pauses in breathing while you sleep. Is a chronic disorder that affects your quality of sleep. Sleep apnea is one of the leading causes of daytime sleepiness increasing the risks of automobile accidents. Deprives you of a restorative sleep you need to be energetic and mentally sharp the next day. How you can help?
These combinations can cause many students to leave little time for adequate studying. In turn, students often pull “all-nighters” cramming for exams or writing papers. They begin to acquire sleep debt, which is an accumulation of many missed hours of needed sleep. Staying up all night cramming for an exam can be detrimental because it causes sleep debt, which in turn impairs memory, interferes with learning processes, and interferes with the ability to evaluate a performance during an exam. The first reason why staying up all night, cramming, is a mistake is because insufficient sleep decreases the ability to remember any new information.
Sleep disturbance: difficulty getting to sleep, staying asleep or especially waking up early. Changes in appetite: usually loss of appetite but sometimes increased appetite. Weight loss or occasionally weight gain, fatigue, decreased energy, difficulty concentrating, thinking or making decisions. Symptoms of delirium: Reduced awareness of the
