This can be explained through an apparent redundancy in the system: A small percentage of Upper limb posterior Lower limb anterior Upper limb lateral Lower limb medial Upper limb posterior Lower limb anterior ("standing on the pyramids") ["Head": fibers travel in trigeminal system] Upper limb Lower limb Figure 7. Patients will present with a characteristic loss of discriminative touch, vibration, and conscious proprioception in the entire body, excluding the head. The Anterolateral System 123 Fasciculus gracilis sensory (discriminative touch, proprioception) from ipsilateral lower limb. Fasciculus cuneatus sensory (discriminative touch, proprioception) from ipsilateral upper limb. Loss of the posterior columns in tabes dorsalis, a sign of neurosyphilis Figure 7. The majority of the fibers travels to the thalamus (spinothalamic tract) and plays a key role in mediating conscious perception or awareness of pain and temperature. Other smaller tracts are involved in modulating these sensations and terminate in various targets in the brainstem and diencephalon. These targets include the midbrain (spinomesencephalic), reticular formation (spinoreticular), brainstem nuclei (spinobulbar), and hypothalamus (spinohypothalamic). The function of these additional tracts is discussed in detail in Chapter 22, "Pain. All of the nerve fibers coming in from the periphery are relatively slowly conducting fibers: either lightly myelinated Ad fibers or unmyelinated C fibers. Ad mechanosensitive fibers and receptors Nondiscriminative touch results from the stimulation of Ad mechanosensitive fibers. Any intense mechanical stimulus that does not result in tissue damage will activate these fibers. A fibers that encode for pain encode primarily for well-localized, sharp primary (or "pricking") pain that is conducted relatively rapidly at 20 m/s. C fibers C fibers are polymodal, having many functions associated with them, and have a slower conduction at 2 m/s. They are the chemonociceptors that are activated by substances released during tissue damage (bradykinin, histamine, changes in pH) and are responsible for the sensation of dull, poorly localized pain. Histamine selective C fibers are responsible for the sensation of itch, and C fibers in muscles convey the burning sensation in muscles that occurs with extreme exercise. C fibers are also sensitive to thermal and mechanical stimulation, similar to A fibers. It is due to their slower conduction velocity that they elicit pain that is dull and poorly localized (often referred to as secondary pain) (Figure 7. General anatomy the neuronal cell bodies of all fibers sensitive to pain and temperature are located in the spinal ganglia. The central processes enter the spinal cord through the posterior horn and ascend or descend a few spinal cord levels in Lissauer tract before entering the gray matter. A great deal of pain modulation occurs in the substantia gelatinosa before the impulse travels to higher cortical centers. This is discussed in more detail in Chapter 22, "Pain", which is dedicated entirely to pain. In the rostral medulla, the anterolateral system lies between the inferior olivary nucleus and the nucleus of the spinal trigeminal tract. In the pons and midbrain, the anterolateral system lies lateral to the medial lemniscus (Figure 7. The fibers in the anterolateral system are arranged somatotopically, with fibers carrying information from the lower limb located more laterally and those carrying information from the upper limb more medially.

In general, the severity of apnea in these older persons is mild (an average apnea index of about 13) compared with that seen in patients with clinical sleep apnea. However, older men and women with mild apnea have been reported to fall asleep at inappropriate times significantly more often than older persons without apnea. Increased mortality rates have been noted in excessively long sleepers, therefore sleep apnea may account for some of these excess deaths. There have been several studies suggesting that untreated sleep apnea in the elderly may lead to shorter survival. The clinical significance of relatively mild "subclinical" sleep apneas is not fully understood yet. Psychiatrists should be aware, however, that such disturbances might be associated with either insomnia or excessive daytime sleepiness. Furthermore, for some patients with sleep apnea, administration of hypnotics, alcohol, or other sedating medications is relatively contraindicated. The risk is not yet known, but reports indicate that benzodiazepines as well as alcohol may increase the severity of mild sleep apnea. Therefore, psychiatrists should inquire about snoring, gasping, and other signs and symptoms of sleep apnea before administering a sleeping pill. Oxygen breathed at night may alleviate insomnia associated with apnea that is not accompanied by impeded inspiration. Surgery may be helpful, for example, to correct enlarged tonsils, a long uvula, a short mandible, or morbid obesity. Pharyngoplasty, which tightens the pharyngeal mucosa and may also reduce the size of the uvula, or the use of a cervical collar to extend the neck, may relieve heavy snoring. Although tricyclic antidepressants are sometimes used in the treatment of clinical sleep apnea in young adults, they may cause considerable toxic effects in older people. The newer shorter-acting nonbenzodiazepine hypnotics seem to be safer in these patients and may be considered in those patients who snore. The disturbance does not occur exclusively during the course of another sleep disorder or other mental disorder. Specify type: Delayed sleep phase type: a persistent pattern of late sleep onset and late awakening times, with an inability to fall asleep and awaken at a desired earlier time Jet lag type: sleepiness and alertness that occur at an inappropriate time of day relative to local time, occurring after repeated travel across more than one time zone Shift work type: insomnia during the major sleep period or excessive sleepiness during the major awake period associated with night shift work or frequently changing shift work Unspecified type Reprinted with permission from the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. Although some individuals do not find this mismatch to be a problem, for others the circadian rhythm disturbance interferes with the ability to function properly at times when alertness or sleepiness is desired or required. For those individuals, insomnia, hypersomnia, sleepiness and fatigue result in significant discomfort and impairment. The circadian rhythm disturbances include delayed sleep phase, advanced sleep phase, shift work, jet lag and non-24-hour-day syndrome. Wrist actigraphs record acceleration of the wrist at frequent intervals, such as every minute, and save it for later display. These individuals are generally not sleepy until several hours after "normal" bedtime. Individuals with delayed sleep phase often choose careers that allow them to set their own schedules, such as freelance writers.

Although there is substantial variation, binges tend to contain 1000 or more calories and to consist of sweet, high-fat foods that are normally consumed as dessert, such as ice cream, cookies and cake. Although patients complain of "carbohydrate craving", they only rarely binge-eat foods that are pure carbohydrates, such as fruits. Patients usually induce vomiting or use their characteristic compensatory behavior immediately after the binge and feel substantial relief that the calories are "gone". In reality, it appears that vomiting is the only purging method capable of disposing of a significant number of ingested calories. The weight loss associated with the misuse of laxatives and diuretics is primarily due to the loss of fluid and electrolytes, not calories. When not binge-eating, patients with bulimia nervosa tend to restrict their calorie intake and to avoid the foods usually consumed during episodes of binge-eating. Although there is some phenomenological resemblance between binge-eating and substance abuse, there is no evidence that physiological addiction plays any role in bulimia nervosa. Assessment Special Issues in Psychiatric Examination and History the assessment of individuals who may have bulimia nervosa is similar to that described for anorexia nervosa. The interviewer should explicitly inquire about self-induced vomiting and whether syrup of ipecac is ever used to promote vomiting. The interviewer should ask about the use of laxatives, diuretics, diet pills and enemas. A weight history should be obtained, so the interviewer can determine whether the binge-eating was preceded by obesity or by anorexia nervosa, as is often the case. Because there is substantial comorbidity, the interviewer should ascertain whether there is a history of anxiety or mood disturbance or of substance abuse. Diagnosis and Differential Diagnosis Phenomenology Bulimia nervosa typically begins after a young woman who sees herself as somewhat overweight starts a diet and, after some initial success, begins to overeat. Distressed by her lack of control and by her fear of gaining weight, she decides to compensate for the overeating by inducing vomiting or taking laxatives, methods Physical Examination and Laboratory Findings the patient should be weighed and the presence of dental erosion noted. Routine laboratory testing reveals an abnormality of fluid and electrolyte balance such as those described in the section on pathophysiology in about 10% of patients with bulimia nervosa. Individuals with the nonpurging form of bulimia nervosa are more likely to be overweight at the time of presentation and to exhibit less general psychiatric illness compared with individuals who induce vomiting. Yes Hospitalization, day program or intensive outpatient program Differential Diagnosis Bulimia nervosa is not difficult to recognize if a full history is available. The binge-eating/purging type of anorexia nervosa has much in common with bulimia nervosa but is distinguished by the characteristic low body weight and, in women, amenorrhea. Some individuals with atypical forms of depression overeat when depressed; if the overeating meets the definition of a binge described previously. Some individuals become nauseated and vomit when upset; this and similar problems are probably not closely related to bulimia nervosa and should be viewed as a somatoform disorder. Many individuals who believe they have bulimia nervosa have a symptom pattern that fails to meet full diagnostic criteria because the frequency of their binge-eating is less than twice a week or because what they view as a binge does not contain an abnormally large amount of food. Individuals with these characteristics fall into the broad and heterogeneous category of atypical eating disorders. The treatment of bulimia nervosa has received considerable attention in recent years and the efficacies of both psychotherapy and medication have been explored in numerous controlled studies (Figure 58. The therapy is focused and highly structured and is usually conducted in 3 to 6 months. The other commonly used mode of treatment that has been examined in bulimia nervosa is the use of antidepressant medication.
