The problem of treatment resistance in bipolar disorder begins with its definition. Characterizing the phases of bipolar disorder as manic, mixed, hypomanic, or depressed does not do justice to the reality for many persons with this disorder.

In 1931, Gananath Sen and Kartick Chandra Bose reported on the use of an alkaloid extract from the Rauwolfia serpentina plant in the treatment of hypertension and "insanity with violent maniacal symptoms." They noted that dosages "of 20 to 30 grains of the powder twice daily produce not only a hypnotic effect but also a reduction of blood pressure and violent symptoms

Parkinson gait is characterized by shuffling, including a decreased stride length and gait speed. The diminished stride and gait speed coupled with increased cadence puts the patient at risk for postural instability resulting in falls.

Delirium is characterized by an altered level of consciousness, decreased attention span, acute onset, and fluctuating course. About 15% of elderly patients admitted to the hospital have delirium as a presenting or associated symptom. Delirium will develop in another 15% of elderly patients during hospitalization.

HHD, which affects only a small percentage (4%) of patients with PD, is characterized by adverse psychomotor effects related to dopamine replacement therapy.

Typical smokers need to have brain nicotine receptors almost completely saturated throughout the day. This need creates an almost uncontrollable urge to keep smoking, commented Nora D. Volkow, MD, director of the National Institute on Drug Abuse (NIDA), addressing a study by NIDA researchers on nicotine addiction.

Hundreds of uniquely adapted venomous marine cone snail species inhabit the coral reefs of the Indian and Pacific oceans. Researchers posit that each may be a virtual neurologic pharmacopoeia with potential value for the treatment of everything from diabetic neuropathy to schizophrenia. The venoms, known as conotoxins, selectively inhibit a wide range of ion channels involved in neuromuscular signaling.

A possible link between diabetes and cognitive dysfunction, specifically Alzheimer disease (AD), is becoming increasingly apparent. Indeed, compared with AD risk in healthy persons, the risk of AD development is 65% to 100% greater in persons with diabetes.

First described more than 500 years ago, phantom limb pain (PLP) is a common disorder today; as many as 50% to 80% of patients who undergo amputation report experiencing pain in the missing appendage.

The editors of Pediatric Neuropsychiatry must have drawn on their experiences and the feedback they received on their first book, Textbook of Pediatric Neuropsychiatry (American Psychiatric Press, 1998), for this text.

Effective treatment of drug abuse and addiction in the criminal justice system saves the community money and reduces crime, the NIH's National Institute on Drug Abuse (NIDA) reported in a recently released booklet, Principles of Drug Abuse Treatment for Criminal Justice Populations.

The increase in youth violence and aggression in the past 50 years has been called an "epidemic." This epidemic has had a tremendous impact on society. From an economic and public health perspective, primary prevention of youth violence is obviously desirable.

Typically, delirium worsens at night ("sundowning"), with lucid intervals often present in the morning. It is important to realize that delirium may appear before any abnormal laboratory values are detected and may persist after the resolution of these abnormalities.

If done properly, the assessment of alcohol and substance use disorders in the emergency department (ED) or psychiatric emergency service can be the first step toward recovery.

The degree to which season changes affect mood, energy, sleep, appetite, food preference, or desire to socialize with others has been called "seasonality." Identification of a seasonal pattern can only be made if both the patient and physician actively look for it.

In a presentation given at the midyear meeting of the American Epilepsy Society, Andres Kanner, MD cited studies from the literature showing that the rates of depression, anxiety, psychosis, and attention-deficit/hyperactivity disorder (ADHD) are significantly higher among persons with epilepsy than among the general population

Most physicians make at least some use of the placebo effect to enhance treatments, whether they realize it or not. This article examines the extent of the placebo effect in patients with psychiatric illness, and reviews what is known about how placebos work.

Alcohol is the drug of choice for adolescents, with cigarettes and marijuana being second and third. Contrary to widespread belief, alcohol dependence is most common in 18- to 20-year-olds, with progressively decreasing rates of alcohol dependence in older age groups.

Depressive disorders and symptoms are common in cancer patients (up to 58% have depressive symptoms and up to 38% have major depression), worsen over the course of cancer treatment, persist long after cancer therapy, recur with the recurrence of cancer, and significantly impact quality of life.

The longitudinal course of bipolar disorder (BD) is characterized by a low rate of recovery, a high rate of recurrence, and poor interepisodic functioning. There is a need to invoke a chronic disease management model (CDMM) when treating individuals with BD.

Complaints of persistent memory loss in otherwise well-functioning individuals after recovery from a psychiatric illness through electroconvulsive therapy (ECT) are best viewed as a conversion reaction or a somatoform disorder. The Camelford experience is a model for the complaints of ECT's profound personal memory losses.

Sleep disorders are very common and are often underrecognized and underreported in children. If left untreated, these disorders can cause serious developmental and physiologic problems.

As Americans' use of personal electronic devices increases, so too, do the controversies surrounding these now seemingly indispensable tools.

Dolls and other toys, such as teddy bears, can alleviate agitation, reduce withdrawal, help overcome communication challenges, and generally improve the quality of life of patients with Alzheimer disease (AD).

Ampakines, agents that have been shown to enhance memory, appear to trigger endogenous brain-derived neurotrophic factor (BDNF), a natural mechanism in the brain that could restore neuronal viability and synaptic plasticity through increased trophic support.
