Treatment-induced mood switching in affective disorders.

Many patients under treatment for mood disorders, in particular patients with bipolar mood disorders, experience episodes of mood switching from one state to another. Various hypotheses have been proposed to explain the mechanism of mood switching, spontaneously or induced by drug treatment. Animal models have also been used to test the role of psychotropic drugs in the switching of mood states.

Hallucinations: diagnosis, neurobiology and clinical management.

Hallucinations are important diagnostic symptoms in schizophrenia, but also occur in other medical and neuropsychiatric conditions. Not all patients with hallucinations are psychotic. There has been a surge of interest in the topic of hallucinations, as new research data have begun to reveal their neurobiology.

Safety of traditional medicine and natural product supplements in psychiatry.

Traditional medicines in the form of health food and supplements are highly popular nowadays. They are often aggressively promoted with unsubstantiated health benefit claims. Patients suffering from chronic illness, such as psychiatric disorders may be attracted to these products and use them concurrently with their prescribed drugs.

Opportunities in Novel Psychotropic Drug Design from Natural Compounds.

Multiple initiatives at the national and international level support natural drug discovery. Psychiatrists and patients are not well informed about natural psychotropics in general. Existing antidepressant and antipsychotic drugs were developed from atropine, a natural product.

Multitarget botanical pharmacotherapy in major depression: a toxic brain hypothesis.

A significant number of patients with major depression do not respond optimally to current antidepressant drugs. As depression is likely to be a heterogeneous disorder, it is possible that existing neurotransmitter-based antidepressant drugs do not fully address other pathologies that may exist in certain cases. Biological pathologies related to depression that have been proposed and studied extensively include inflammation and immunology, hypercortisolemia, oxidative stress, and impaired angiogenesis.

Herbal medicine for psychiatric disorders: Psychopharmacology and neuroscience-based nomenclature.

Herbs are frequently and concurrently used with prescribed drugs by patients worldwide. While clinical trials have found some herbs to be as useful as standard psychiatric drugs, most clinicians are unaware of their pharmacological mechanisms. We searched English language and other language literature with English abstracts listed in PubMed website, supplemented by additional through Google Scholar's free academic paper abstract website for publications on herbs, focussing on their clinical use in mental disorders, their neurobiology and their pharmacology.

Managing interactions between cognitive enhancers and other psychotropics.

Polypharmacy is common in psychiatry. Usage of cognitive enhancers is increasing in the psychiatric population. Many clinicians are not familiar with these new psychoactive compounds.
