PCP is used by persons who tend to be multiple drug users. PCP is one of the more common drugs found in arrestee populations, although its prevalence varies considerably by jurisdiction. An unknown, but probably very small percentage of users suffer extreme PCP-induced intoxication and disorientation and commit bizarre, often violent acts. Much more research is needed to identify the extent of these problems in users, and to learn how personality, other drug use, and the quality and quantity of PCP ingested contribute to the occurrence of violent behavior. (Wish and Johnson, in press)... 

Another implication of the large numbers of arrestees who use PCP is that only a small percentage of users probably experience the bizarre, violent behavior that is often attributed to PCP. If more than one or two percent of the arrestees in New York City and Washington, D.C. were to experi ence violent psychotic-like behavior when they use PCP, the police and treatment resources in these cities would be overburdened by the problem. Furthermore, these estimates do not include the many users of PCP who are never arrested. 

In adult patients, the manifestations of PCP use can be grouped into nine clinical patterns of intoxication. Four of these are called major patterns because they may be associated with severe toxicity and often necessitate hospitalization. Patients with major patterns are usually unpredictable symptoms wax and wane, and the patient may abruptly change from one pattern of intoxication to another. Five other symptom complexes are designated as minor patterns since toxicity is usually mild and of short duration. Major Patterns consist of coma, catatonic syndrome, toxic psychosis, and acute brain syndrome. Minor Patterns are lethargy, bizarre behavior, violent behavior, agitation, and euphoria (McCarron et al. 1981b).

McCarron s paper (this volume) describes the behaviors of 1,000 adults admitted to an inpatient service with acute symptoms of PCP intoxication. She states that some of the patients have appropriate behavior while many have mute and staring episodes, bizarre facial grimacing, localized dystonic reactions, rigidity, tremors, coarse jerky movements, and nystagmus. Thus, there is similarity between the acutely intoxicated adult s behavior and that of the newborn with a positive urine toxic screen for PCP. 

Patients presenting with odd behaviors, illogical thought processes, bizarre beliefs, and hallucinations should be assessed for schizophrenia.

One of the most sensitive systems affected by lead exposure is the nervous system. Encephalopathy is characterized by symptoms such as coma, seizures, ataxia, apathy, bizarre behavior, and incoordination (CDC 1985). Children are more sensitive to neurological changes. In children, encephalopathy has been associated with PbB levels as low as 70 pg/dL (CDC 1985). The most sensitive peripheral index of neurotoxicity of lead is reported to be slowed conduction in small motor libers of the ulnar nerve in workers with 30-40 pg/dL lead in blood (Landrigan 1989). Other potential biomarkers of lead suggested for neurotoxicity in workers are neurological and behavioral tests, as well as cognitive and visual sensory function tests (Williamson and Teo 1986). However, these tests are not specific to elevated lead exposure... 

Acute mania usually begins abruptly, and symptoms increase over several days. The severe stages may include bizarre behavior, hallucinations, and paranoid or grandiose delusions. There is marked impairment in functioning or the need for hospitalization. 

Even children are not immune from poisoning by PCP. Six cases were observed at the UCLA Medical Center, all 5 years old or younger. Presumably, most were poisoned by accidental ingestion of the drug, which was available in the house one child, only 11 days old, was presumably poisoned by passive inhalation of the smoke produced by the adults around him. The most common clinical manifestations in these youngsters was bizarre behavior, lethargy, ataxia, and nystagmus (48). 

Species of Datura, Hyoscyamus and other tropane-containing genera are of more risk to humans than animals. These plants and their seeds have been used for religious or social functions with ritualistic emphasis. Numerous cases of bizarre and often aggressive behavior have been reported in people using seeds or teas from these plants (Burrows and Tyrl, 2002). As recently as October of 2003, a report appeared at CNN.com of four teenagers who ate Jimson weed seeds. All hallucinated and had to be hospitalized. Two were sedated and placed on life-support to prevent danger to themselves and others. The same press release reported that Centers for Disease Control and Prevention... 

Excess consumption of alcohol is not healthful, as many people will testify. Ethanol is a depressant and can be a mild tranquilizer or a general anesthetic, depending on how much is consumed over what period of time. At low doses, ethanol depresses some of the brain s inhibitory systems and acts as a social lubricant. It can also exacerbate seizure disorders such as epilepsy by depressing the inhibitory systems in the brain that suppress seizures and convulsions. At higher doses, alcohol leads to the classical symptoms of intoxication unsteady walk, slurred speech, altered sensory perception, slow reaction times, bizarre behavior, and finally, loss of consciousness. Consnmption of a fiffh of a gallon of hard liqnor over a short time period can be fatal. 

The initial presentation is usually in the context of a crisis that has triggered the acute phase of the illness or a crisis that has arisen as a consequence of the illness. At this point the behavior has become so bizarre or the social deterioration so pronounced that it could no longer go unnoticed. 

Other Hypersomnias. Narcolepsy is not the only hypersomnia, but it is by far the most common. Primary hypersomnia shares sleep attacks and excessive daytime sleepiness with narcolepsy but does not feature cataplexy or REM-associated abnormalities. Another rare hypersomnia is Kleine-Levin syndrome (KLS), which most often occurs in teenage boys. KLS consists of intermittent bouts of hypersomnia and bizarre behaviors including compulsive eating and sexual inappropriateness. Distinguishing these hypersomnias from narcolepsy may help clarify the patient s prognosis, but the treatment alternatives are very similar. 

Lower zone loops that are not shaped normally. These bizarre lower zone loops signify the sex/relationship aspect of the writer s life is unusual. If tlie loops are large, as shown, the sexual appetite crosses the line into sexual behavior outside the norm. 

Behavior changes Isolated instances of bizarre behavior, including mental confusion and visual hallucinations, have been reported in patients taking benzonatate in combination with other prescribed drugs. 

Rabies. An acute infectious disease of the central nervous system affecting most mammals including humans, caused by rhabdovi-rus. Typical symptoms include paresthesia and a burning sensation or pain at the site of inoculation, periods of hyperexcitability, agitation, delirium, hallucinations, and bizarre behavior, between which the person is often cooperative and lucid.
