The DRD2 and ANKK1 genes are located approximately 10,000 nucleotides apart on chromosome llq22-23. Variants in both genes have been found to be associated with several psychiatric diseases such as schizophrenia, as well as with substance abuse disorders, including alcohol, heroin, nicotine, cocaine, opioid, gambling, methamphetamine, and polysubstance addiction [30-37]. 

Glassification of Substance-Related Disorders. The DSM-IV classification system (1) divides substance-related disorders into two categories (/) substance use disorders, ie, abuse and dependence and (2) substance-induced disorders, intoxication, withdrawal, delirium, persisting dementia, persisting amnestic disorder, psychotic disorder, mood disorder, anxiety disorder, sexual dysfunction, and sleep disorder. The different classes of substances addressed herein are alcohol, amphetamines, caffeine, caimabis, cocaine, hallucinogens, inhalants, nicotine, opioids, phencyclidine, sedatives, hypnotics or anxiolytics, polysubstance, and others. On the basis of their significant socioeconomic impact, alcohol, nicotine, cocaine, and opioids have been selected for discussion herein.

Comparable findings for lifetime prevalence of psychiatric disorders were obtained in another study of 133 persons, which also found that 47% received a concurrent DSM-III diagnosis of substance abuse or dependence (Khantzian and Treece 1985). The most frequently abused substances were sedative-hypnotics (23%), alcohol (14%), and cannabis (13%). Similar rates of psychiatric disorders were found in other studies of drug abusers (Mirin et al. 1986 Woody et al. 1983). Although such diagnoses do not imply causality, and, in many cases, opioid dependence causes or exacerbates psychiatric problems, some causal link seems likely (Regier et al. 1990). 

Benzodiazepines have a low risk for abuse in anxiety disorder patients without a history of alcohol or other substance abuse. Among the benzodiazepines there may be a spectrum of abuse liability, with drugs that serve as prodrugs for desmethyldiazepam (e.g., clorazepate), slow-onset agents (e.g., oxazepam), and partial agonists (e.g., abecarnil) having the least potential for abuse. However, there is no currently marketed benzodiazepine or related drug that is free of potential for abuse.

It is considered a second-line agent for GAD because of inconsistent reports of efficacy, delayed onset of effect, and lack of efficacy for comorbid depressive and anxiety disorders (e.g., panic disorder or SAD). It is the agent of choice in patients who fail other anxiolytic therapies or in patients with a history of alcohol or substance abuse. It is not useful for situations requiring rapid antianxiety effects or as-needed therapy.

When diagnosing a substance use disorder, it is named in accordance with the substance that is being misused. Patients can be said to have alcohol abuse or dependence, cocaine abuse or dependence, opiate abuse or dependence, and so forth. In severe cases when the patient is misusing several substances, (s)he is diagnosed with polysubstance dependence. The complete list of DSM-IV substance use disorders is shown in Table 6.3. Although the diagnostic criteria for the specific substance use disorders are uniform from substance to substance, certain features of the addiction are specihc to the substance being misused. The typical age of onset, the course of the disorder, and the treatment of the disorder vary by substance. Nevertheless, many features of substance abuse and substance dependence are similar across substances. 

Naltrexone is prescribed at a dose of 50 mg once per day for at least 12 weeks as part of a comprehensive alcohol treatment program. Like all treatments for substance use disorders, it works only as well as the addict allows it to work. This is why it is important to use it as a component of an overall treatment plan. Otherwise, poorly motivated alcohol abusers will seldom remain adherent with naltrexone and it will have little chance of providing benefit. A long-acting depot formulation of naltrexone currently in development might improve these compliance problems. 

OCD is also frequently comorbid with AN in fact, some researchers posit that the eating disorders are a modern variant of OCD peculiar to Western culture. In particular, the propensity for excessive exercise among some patients with AN may indicate the presence of comorbid OCD. Finally, the abuse of alcohol and other substances commonly complicates the presentation and course of AN. Comorbid substance abuse will likely undermine any progress in the treatment of AN and... 

Once chronic insomnia has developed, it hardly ever spontaneously resolves without treatment or intervention. The toll of chronic insomnia can be very high and the frustration it produces may precipitate a clinical depression or an anxiety disorder. Insomnia is also associated with decreased productivity in the workplace and more frequent use of medical services. Einally, substance abuse problems may result from the inappropriate use of alcohol or sedatives to induce sleep or caffeine and other stimulants to maintain alertness during the day. 

Substance Use Disorder. Patients abusing alcohol or other substances may be prone to erratic behavior reminiscent of the Cluster B personality disorders. If these behaviors occur exclusively in a context of intoxication or during periods of heavy substance use, then the diagnosis of a Cluster B personality disorder is not warranted. Instead, treatment should be focused on the substance use disorder. This is not to say, however, that substance use disorders and Cluster B personality disorders cannot occur together. In fact, the difficulty that these patients have in self-soothing leaves them especially vulnerable to substance abuse. 

Within this Held, most of the research and results have been focused on the effects of drug therapy on the disorders induced by alcohol, and by the abuse of opiates. For a broader discussion of substance abuse see Chapter 18. In all instances of alcohol or drug abuse the first objective is to wean the patients from the addictive substance, treating or preventing the effects of withdrawal for those substances which cause physical dependence (alcohol, nicotine, opiates, caffeine, certain psychotropic agents such as benzodiazepines, possibly antidepressants). The second phase is the prevention of recurrence or relapse, which relies on a combination of social support, psychotherapy, and pharmacotherapy where available. In this respect, alcoholism is exemplary. 

Although genetic influences on the dynamics of drug response have been studied in a wide range of disorders, most of the studies have been carried out in only the past few years. Disorders and behaviors studied include Alzheimer s disease, schizophrenia, depression, suicide, anxiety, obsessive-compulsive disorder (OCD), substance abuse, smoking, and alcoholism. Across these disorders, however, there has been a focus on only a handful of neuroeffector systems. These include apolipoprotein and the cholinergic system (in Alzhei-...
