In fact, this relationship is so robust that some view the presence of RBD as a potential aid in the diagnosis and treatment of a number of neurodegenerative diseases (Ferini-Strambi, 2011). Opium, Heroin, Fentanyl, Morphine, Oxycodone, Vicoden, methadone, and other prescription pain relievers, Decreased pain, pupil dilation, decreased gut motility, decreased respiratory function. Social programs like Medicare: a - offer health coverage for the older adults 24. Stage 1 sleepis a transitional phase that occurs between wakefulness and sleep, the period during which we drift off to sleep. Scott Falater had a history of regular episodes of sleepwalking as a child, and he had even behaved violently toward his sister once when she tried to prevent him from leaving their home in his pajamas during a sleepwalking episode. It may surprise you to know that sleep deprivation is associated with obesity, increased blood pressure, increased levels of stress hormones, and reduced immune functioning (Banks & Dinges, 2007). While hypnosis may be useful in enhancing memory or a skill, such enhancements are very modest in nature (Raz, 2011). This disorder is associated with a number of neurodegenerative diseases such as Parkinsons disease. Humans have an endogenous opioid neurotransmitter systemthe body makes small quantities of opioid compounds that bind to opioid receptors reducing pain and producing euphoria. When we do this, we often experience jet lag. In addition, if a pregnant woman consumes alcohol, her infant may be born with a cluster of birth defects and symptoms collectively called fetal alcohol spectrum disorder (FASD) or fetal alcohol syndrome (FAS). Add a comment. The term was first coined by a physiologist named Walter Cannon in 1926. Alan Hobson, a neuroscientist, is credited for developing activation-synthesis theory of dreaming. Again, this is an intuitive and appealing explanation for why we sleep. Thus we sleep in safe areas to reduce the chance of harm. The freebase version of cocaine, known as crack, is a potent, smokable version of the drug. This section will consider these questions and explore various explanations for why we sleep. Marijuana, LSD, Peyote, mescaline, DMT, dissociative anesthetics including ketamine and PCP, Increased heart rate and blood pressure that may dissipate over time, Mild to intense perceptual changes with high variability in effects based on strain, method of ingestion, and individual differences, Understand what is meant by consciousness, Explain how circadian rhythms are involved in regulating the sleep-wake cycle, and how circadian cycles can be disrupted, Describe areas of the brain involved in sleep, Understand hormone secretions associated with sleep, Describe several theories aimed at explaining the function of sleep, Differentiate between REM and non-REM sleep, Describe the differences between the three stages of non-REM sleep, Understand the role that REM and non-REM sleep play in learning and memory, Describe the symptoms and treatments of insomnia, Recognize the symptoms of several parasomnias, Describe the symptoms and treatments for sleep apnea, Recognize risk factors associated with sudden infant death syndrome (SIDS) and steps to prevent it, Describe the symptoms and treatments for narcolepsy. (credit: Laurie Avocado). We might also experience unconscious states of being via drug-induced anesthesia for medical purposes. Stage 2 sleep is characterized by the appearance of both sleep spindles and K-complexes. Primary signs and symptoms of Ebola often include some or several of the following: Fever. c. While there are variations, there are four parts that appear consistent in bringing people into the state of suggestibility associated with hypnosis (National Research Council, 1994). Treatment. Once awakened from a narcoleptic attack, people report that they feel refreshed (Chokroverty, 2010). Night terrors apparently occur during the NREM phase of sleep (Provini, Tinuper, Bisulli, & Lagaresi, 2011). While there is tremendous variation in any given individuals sleep needs, the National Sleep Foundation (n.d.) cites research to estimate that newborns require the most sleep (between 12 and 18 hours a night) and that this amount declines to just 79 hours by the time we are adults. C) the severity and duration of the problem. While amphetamines are often abused, they are also commonly prescribed to children diagnosed with attention deficit hyperactivity disorder (ADHD). Evolutionary psychologyis a discipline that studies how universal patterns of behavior and cognitive processes have evolved over time as a result ofnatural selection. The hypnogram below (Figure 4.12) shows a persons passage through the stages of sleep. There is a trend that females report more somatic symptoms than males; thus, more females are diagnosed with somatic symptom disorder than males (APA, 2022). Theta wavesare even lower frequency (47 Hz), higher amplitude brain waves than alpha waves. With repeated use of many central nervous system depressants, such as alcohol, a person becomes physically dependent upon the substance and will exhibit signs of both tolerance and withdrawal. Surprisingly, narcoleptic episodes are often triggered by states of heightened arousal or stress. If you get peritoneal dialysis, peritonitis symptoms also may include: Cloudy dialysis fluid. In the central nervous system, it plays a role in arousal and reward mechanisms. (credit sleeping: modification of work by Ryan Vaarsi). (West et al., 2009, p. 114). In fact, abuse of prescription opioid medications is becoming a major concern worldwide (Aquina, Marques-Baptista, Bridgeman, & Merlin, 2009; Casati, Sedefov, & Pfeiffer-Gerschel, 2012). Like many other stimulants, cocaine agonizes the dopamine neurotransmitter system by blocking the reuptake of dopamine in the neuronal synapse. Upon admission to an outpatient clinic for treatment of mood disorders, she met all of the diagnostic criteria for substance dependence and was advised to dramatically limit her caffeine intake. 22. Chronic insomnia is almost always associated with feeling overtired and may be associated with symptoms of depression. Has something like this ever happened to you? While we have discussed the negative outcomes associated with sleep deprivation, it should be pointed out that there are many benefits that are associated with adequate amounts of sleep. The participant is encouraged to use his or her imagination. In 2012, Kromann and Nielson reported on a case study of a 40-year-old woman who suffered significant ill effects from her use of caffeine. For example, the National Institutes of Drug Abuse has sponsored research that suggests the misuse and abuse of the prescription pain killers hydrocodone and oxycodone are significant public health concerns (Maxwell, 2006). On January 16, 1997, Scott Falater sat down to dinner with his wife and children and told them about difficulties he was experiencing on a project at work. Brainwave activity changes dramatically across the different stages of sleep. If people are deprived of REM sleep and then allowed to sleep without disturbance, they will spend more time in REM sleep in what would appear to be an effort to recoup the lost time in REM. (credit: modification of work by new 1lluminati/Flickr), Medical marijuana shops are becoming more and more common in the United States. Sleep-wake cycles seem to be controlled by multiple brain areas acting in conjunction with one another. The substantial amount of research on SIDS has led to a number of recommendations to parents to protect their children (Figure 4.14). While people are often unaware of their sleep apnea, they are keenly aware of some of the adverse consequences of insufficient sleep. Recently, a new EPAP (expiratory positive air pressure) device has shown promise in double-blind trials as one such alternative (Berry, Kryger, & Massie, 2011). Table 4.1shows the new recommendations, which describe sleep durations that are recommended, may be appropriate, and not recommended. In her case, the fact that her cataplexy was confined to the right side of her body was quite unusual. While disruptions in circadian rhythms can have negative consequences, there are things we can do to help us realign our biological clocks with the external environment. High doses increase agitation, paranoia, can cause hallucinations. For individuals who are especially open to the power of suggestion, hypnosis can prove to be a very effective technique, and brain imaging studies have demonstrated that hypnotic states are associated with global changes in brain functioning (Del Casale et al., 2012; Guldenmund, Vanhaudenhuyse, Boly, Laureys, & Soddu, 2012). c. absence of subjective symptoms of disease. A number of risk factors have been associated with SIDS including premature birth, smoking within the home, and hyperthermia. In contrast,non-REM (NREM)sleep is subdivided into four stages distinguished from each other and from wakefulness by characteristic patterns of brain waves. Stimulantsare drugs that tend to increase overall levels of neural activity. In the brain, the hypothalamus, which lies above the pituitary gland, is a main center of homeostasis. Case fatality rates have varied from 25% to 90 . The brains clock mechanism is located in an area of the hypothalamus known as thesuprachiasmatic nucleus (SCN). Furthermore, these types of behaviors ultimately disrupt sleep, although affected individuals have no memories that these behaviors have occurred (Arnulf, 2012). Jet lag is a collection of symptoms that results from the mismatch between our internal circadian cycles and our environment. For example, a person may work from 7:00 a.m. to 3:00 p.m. on Monday, 3:00 a.m. to 11:00 a.m. on Tuesday, and 11:00 a.m. to 7:00 p.m. on Wednesday. Some animals never sleep (e.g., some fish and amphibian species); other animals sleep very little without apparent negative consequences (e.g., giraffes); yet some animals (e.g., rats) die after two weeks of sleep deprivation (Siegel, 2008). Feeling tired. REM sleep behavior disorder (RBD)occurs when the muscle paralysis associated with the REM sleep phase does not occur. As you will learn when you study social roles, peoples behavior can be shaped by their expectations of how they should act in a given situation. While medical marijuana laws have been passed on a state-by-state basis, federal laws still classify this as an illicit substance, making conducting research on the potentially beneficial medicinal uses of marijuana problematic. Some forms of psychotherapy, such as cognitive-behavioral therapy, can help sufferers of insomnia. Remarkably, Falater insisted that he had no recollection of hurting his wife in any way. Diarrhea. In other words, physical dependence in and of itself is of limited utility in determining whether or not someone has a substance use disorder. A person withrestless leg syndromehas uncomfortable sensations in the legs during periods of inactivity or when trying to fall asleep. The consequences of sleep debt include decreased levels of alertness and mental efficiency. As already mentioned, the hypothalamus contains the SCNthe biological clock of the bodyin addition to other nuclei that, in conjunction with the thalamus, regulate slow-wave sleep. In the latter part of 2013, however, the United States Department of Justice issued statements indicating that they would not continue to challenge state medical marijuana laws. Some people who have injected many times into their arms will show track marks, while other users will inject into areas between their fingers or between their toes, so as not to show obvious track marks and, like all abusers of intravenous drugs, have an increased risk for contraction of both tuberculosis and HIV. Insudden infant death syndrome (SIDS)an infant stops breathing during sleep and dies. There may also be differences in both brain structure and function in infants that die from SIDS (Berkowitz, 2012; Mage & Donner, 2006; Thach, 2005). Wakefulnessis characterized by high levels of sensory awareness, thought, and behavior. Our states of consciousness change as we move from wakefulness to sleep. The suprachiasmatic nucleus (SCN) serves as the brains clock mechanism. Therefore, the abuse potential of central nervous system depressants is relatively high. For example, Hobson (2009) suggests that dreaming may represent a state of protoconsciousness. An important difference between mood disorders and normal mood fluctuation is: A) the particular medication used to treat the problem. Sleepwalking most often occurs during slow-wave sleep, but it can occur at any time during a sleep period in some affected individuals (Mahowald & Schenck, 2000). Sleep is not a uniform state of being. Research indicates that included among these possible benefits are increased capacities for creative thinking (Cai, Mednick, Harrison, Kanady, & Mednick, 2009; Wagner, Gais, Haider, Verleger, & Born, 2004), language learning (Fenn, Nusbaum, & Margoliash, 2003; Gmez, Bootzin, & Nadel, 2006), and inferential judgments (Ellenbogen, Hu, Payne, Titone, & Walker, 2007). People vary in terms of their ability to be hypnotized, but a review of available research suggests that most people are at least moderately hypnotizable (Kihlstrom, 2013). The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. One or two nights of sleep difficulty is not unusual, but if you experience anything more than that, you should seek a doctors advice. There are two types of sleep apnea: obstructive sleep apnea and central sleep apnea. Dreams and their associated meanings vary across different cultures and periods of time. It is also associated with paralysis of muscle systems in the body with the exception of those that make circulation and respiration possible. The participant is made comfortable and is directed to be relaxed and sleepy. Two sleeping children are depicted in this 1895 oil painting titled. Many of these processes, like much of psychological behavior, are rooted in our biology. Some view a hypnotized persons behavior not as an altered or dissociated state of consciousness, but as their fulfillment of the social expectations for that role (Coe, 2009; Coe & Sarbin, 1966). As scary as it sounds, many sleep researchers believe that homicidal sleepwalking is possible in individuals suffering from the types of sleep disorders described below (Broughton et al., 1994; Cartwright, 2004; Mahowald, Schenck, & Cramer Bornemann, 2005; Pressman, 2007). Anopioidis one of a category of drugs that includes heroin, morphine, methadone, and codeine. Sleep regulationrefers to the brains control of switching between sleep and wakefulness as well as coordinating this cycle with the outside world. Other drugs, including the opioid buprenorphine, have also been used to alleviate symptoms of opiate withdrawal. These include daydreaming, intoxication, and unconsciousness due to anesthesia. Just as bears hibernate in the winter when resources are scarce, perhaps people sleep at night to reduce their energy expenditures. Variations and adaptations in cognition and behavior make individuals more or less successful in reproducing and passing their genes to their offspring. Thus, opioid drugs, which mimic this endogenous painkilling mechanism, have an extremely high potential for abuse. That includes exercise and bright light from devices. For example, body temperature fluctuates cyclically over a 24-hour period (Figure 4.2). Meditative techniques have their roots in religious practices (Figure 4.21), but their use has grown in popularity among practitioners of alternative medicine. After dinner, he prepared some materials to use in leading a church youth group the following morning, and then he attempted to repair the familys swimming pool pump before retiring to bed. . People who suffer from insomnia might limit their use of stimulant drugs (such as caffeine) or increase their amount of physical exercise during the day. While hypnosis is generally achieved through the interaction of a therapist and the person being treated, an individual can perform meditation alone. The lifespan perspective in health psychology reveals that adolescents One of the shortcomings with the health belief model is Risk factors for a health problem People whose personalities include high levels of _____ seem to be "disease" For example, most people sleep during the night and are awake during the day. (a) Common paraphernalia for heroin preparation and use are shown here in a needle exchange kit. High doses can cause death due to respiratory depression. Melatonin is thought to be involved in the regulation of various biological rhythms and the immune system (Hardeland et al., 2006). Freud made distinctions between the manifest content and the latent content of dreams. Some circadian rhythms play a role in changes in our state of consciousness. Keep your bedroom temperature between 60 and 67 degrees. Nicotine exerts its effects through its interaction with acetylcholine receptors. You were capable of engaging in the all of the complex tasks involved with operating a motor vehicle even though you were not aware of doing so. Popular portrayals of hypnosis have led to some widely-held misconceptions. Alertness is associated with higher body temperatures, and sleepiness with lower body temperatures. Opioids have analgesic properties; that is, they decrease pain. Surprisingly, sleep apnea may exacerbate cardiovascular disease (Snchez-de-la-Torre, Campos-Rodriguez, & Barb, 2012). In such instances, the individuals schedule changes so frequently that it becomes difficult for a normal circadian rhythm to be maintained. It is relatively easy to wake someone from stage 1 sleep; in fact, people often report that they have not been asleep if they are awoken during stage 1 sleep. In 2015, the National Sleep Foundation updated their sleep duration hours, to better accommodate individual differences. There are now several synthetic versions of opiate drugs (correctly called opioids) that have very potent painkilling effects, and they are often abused. Awareness of internal stimuli includes feeling pain, hunger, thirst, sleepiness, and being aware of our thoughts and emotions. B) the cause of the problem. Interestingly, individuals who have increased levels of alpha brain wave activity (more often associated with wakefulness and transition into stage 1 sleep) during stage 3 often report that they do not feel refreshed upon waking, regardless of how long they slept (Stone, Taylor, McCrae, Kalsekar, & Lichstein, 2008). These symptoms include fatigue, sluggishness, irritability, and insomnia (i.e., a consistent difficulty in falling or staying asleep for at least three nights a week over a month's time) (Roth, 2007). Codeineis an opioid with relatively low potency. Homeostasis refers to the body's need to reach and maintain a certain state of equilibrium. Latent content, on the other hand, refers to the hidden meaning of a dream. Normal brain functioning is altered after repeated use of these drugs. Large-scale public health campaigns by the National Institutes of Health and the National Institute of Drug Abuse have led to recent declines in the opioid crisis. Methadone clinicshelp people who previously struggled with opioid addiction manage withdrawal symptoms through the use of methadone. Rather, the ISS r ecognizes mixed states and depressive symptoms during manic and hypomanic episodes. Once she was able to limit her use to less than 12 ounces of soda a day, both her mental and physical health gradually improved. b. life expectancy has reached a new high. A) a mole that looks cancerous B) nasal congestion C) change in heart rate D) issues with breathing Which of the following American health care systems is most known for requiring a referral from a primary care doctor in order to see a specialist? Drug withdrawal is usually an aversive experience, and it can be a life-threatening process in individuals who have a long history of very high doses of alcohol and/or barbiturates. An agonist facilitates the activity of a neurotransmitter system, and antagonists impede neurotransmitter activity. The low cost coupled with lower risk of overdose than with opiate drugs is making crystal meth a popular choice among drug users today (NIDA, 2019). You have read that the pineal gland releases melatonin during sleep (Figure 4.6). This chart illustrates the circadian change in body temperature over 28 hours in a group of eight young men. Sleep apneais defined by episodes during which a sleepers breathing stops. However, for some, its not because of all-night partying or late-night study sessions. Unexplained hemorrhaging, bleeding or bruising. 1. There are a variety of drugs that treat restless leg syndrome: benzodiazepines, opiates, and anticonvulsants (Restless Legs Syndrome Foundation, n.d.). typically follow the example of their parents more than their friends. The fifth edition of theDiagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5) is used by clinicians to diagnose individuals suffering from various psychological disorders. In some cases, users experience vivid visual hallucinations. These drugs promote increased levels of neural activity.
