Mental and Behavioral Disorders
Introduction to Mental and Behavioral Health
• One of every four American adults and children has been diagnosed with a mental condition.
• More than 30% of the 20 top-selling medications are for psychiatric disorders.
• The fourth most common diagnostic category for inpatient admissions is substance-related mental disorders.
• Approximately 40 million Americans are diagnosed with anxiety.
• The number of discharges for patients with substance-related mental health disorders has sharply escalated, from 20,000 in 1998 to 110,000 in 2008.
• Approximately 7.5 million Americans are classified as mentally retarded.
• Given these statistics, the terminology related to mental and behavioral disorders is content that cannot be ignored.
Similar to previous chapters, this chapter examines disorders that result when an individual has a maladaptive response to his or her environment (internal or external). (See Chapter 11 for an explanation of the anatomy and physiology of the brain and nervous system.) However, even though some mental illnesses have organic causes in which neurotransmitters and other known brain functions play a role, there is no mental “anatomy” per se. Instead, behavioral health is a complex interaction among an individual’s emotional, physical, mental, and behavioral processes in an environment that includes cultural and spiritual influences.

Procedures
Diagnostic Procedures
Imaging
Imaging is most helpful in ruling out neurologic disorders and in research; it is less helpful in diagnosing or treating psychiatric problems. Computed tomography (CT) scans and magnetic resonance imaging (MRI) can be used to screen for brain lesions. Positron emission tomography (PET) scans can be used to examine and map the metabolic activity of the brain (Fig. 12-3). Central nervous system imaging in ICD-10-PCS is coded as plain radiography, fluoroscopy, CT scans, MRIs, or ultrasonography. The body part characters will be familiar from coverage of the nervous system, while the detail includes the type of contrast and whether it is unenhanced or enhanced.
Psychological Testing and Treatment
Bender Gestalt test: a test of visuomotor and spatial abilities; useful for children and adults.
Cognistat: also called the Neurobehavioral Cognitive Status Examination (NCSE), this is a test to measure a patient’s abilities in five areas to test their cognitive abilities. It is used to measure disability in patients with substance abuse, strokes, and traumatic brain injuries.
Draw-a-Person (DAP) Test: analysis of patient’s drawings of male and female individuals. Used to assess personality.
Minnesota Multiphasic Personality Inventory (MMPI): assessment of personality characteristics through a battery of forced-choice questions.
Rorschach: a projective test using inkblots to determine the patient’s ability to integrate intellectual and emotional factors into his or her perception of the environment.
Thematic Apperception Test (TAT): a test in which patients are asked to make up stories about the pictures they are shown. This test may provide information about a patient’s interpersonal relationships, fantasies, needs, conflicts, and defenses.
Wechsler Adult Intelligence Scale (WAIS): a measure of verbal IQ, performance IQ, and full-scale IQ.
Wechsler Intelligence Scale for Children (WISC): a measure of intellectual development in children.

Pharmacology
antialcoholics: Discourage use of alcohol. Naltrexone (ReVia) can be used for alcohol and narcotic withdrawal. Disulfiram (Antabuse) is used to deter alcohol consumption.
antidepressants: Relieve symptoms of depressed mood. Many drug classes are available, including selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants (TCAs), monoamine oxidase inhibitors (MAOIs), and some newer unclassified agents. Examples include fluoxetine (Prozac), sertraline (Zoloft), mirtazapine (Remeron), bupropion (Wellbutrin), and venlafaxine (Effexor).
antipsychotics or neuroleptics: Control psychotic symptoms such as hallucinations and delusions. Haloperidol (Haldol) and chlorpromazine (Thorazine) are examples of typical antipsychotics; olanzapine (Zyprexa) and risperidone (Risperdal) are examples of the newer atypical antipsychotics.
anxiolytics: Relieve symptoms of anxiety. These drugs are often used as sedatives or sedative-hypnotics as well. Examples are lorazepam (Ativan), buspirone (BuSpar), and alprazolam (Xanax).
cholinesterase inhibitors: Combat the cognitive deterioration seen in disorders characterized by dementia, such as Alzheimer’s disease. Also known as acetylcholinesterase inhibitors (AChEIs). Examples are donepezil (Aricept) and galantamine (Reminyl, Razadyne).
hypnotics: Promote sleep. Hypnotics, sedatives, sedative-hypnotics, and anxiolytics are often similar in effect and may be used interchangeably. Zolpidem (Ambien), zaleplon (Sonata), and flurazepam (Dalmane) are examples of hypnotics.
mood stabilizers: Balance neurotransmitters in the brain to reduce or prevent acute mood swings (mania or depression). Lithium (Lithobid) is the most well-known mood stabilizer. Some anticonvulsants such as valproic acid (Depakote) and lamotrigine (Lamictal) are also considered mood stabilizers.
NMDA receptor antagonists: Preserve cognitive function in patients suffering from progressive memory loss by blocking glutamate activity. Memantine (Namenda) is the only drug of this class currently used for this purpose.
sedatives and sedative-hypnotics: Exert a calming effect with or without inducing sleep. The most commonly used agents are benzodiazepines and barbiturates.
stimulants: Generally increase synaptic activity of targeted neurons to increase alertness. Examples include methylphenidate (Ritalin) and caffeine.
