Natural substances in psychiatry (Ginkgo biloba in dementia).

Natural substances and/or their synthetically developed active ingredients are frequently used in medicine. In psychiatry, two of the most well known natural compounds are reserpine and Ginkgo biloba extract (EGb). EGb is among the most popular over-the-counter medicines in Europe and is also available in the United States, primarily in health food stores. Already the European medical community has recognized EGb as an effective compound in the treatment of cerebral insufficiency. In a pilot bioequivalency study, the effects of three different commercially available EGb products were examined. Findings indicated significant quantitative central nervous system (CNS) effects in, at least, one of the three. Furthermore, the CNS effects of Ginkgold were similar to other psychoactive compounds classified as cognitive activators. Recent studies in which EGb 761 demonstrated therapeutic effects in the treatment of dementia have earned EGb the approval of the German BGA (Bundesgesundheit Amt) for use in the treatment of dementia.

Discrimination of mode of action of anxiolytics using an integrated computer data bank and Dynamic Brain Mapping (CNS effects of diazepam and lorazepam).

In a double-blind, placebo-controlled, crossover study, the CNS effects of intravenously administered diazepam and lorazepam were investigated in anxious subjects through the quantitative pharmaco-EEG (QPEEG) method. For up to 4 1/2 hours following administration the effects of each substance on brain function were measured using computer analyzed EEG recordings (CEEG) and a new technique called Dynamic Brain Mapping. The following observations were made: 1. Both active drugs produce statistically significant CNS effects as measured by CEEG changes. These changes were observed earlier with diazepam than with lorazepam. 2. Although both compounds are classified as anxiolytic by the routine computer EEG data base, the detailed brain mapping technology indicated that the CNS effects of diazepam and lorazepam were quantitatively and qualitatively different. 3. Clinical CNS side-effects (sedation) were seen more frequently with lorazepam than with diazepam. This was consistent with the EEG slowing producing properties of lorazepam. The EEG fast activity which is characteristic for all anxiolytics was established more with diazepam than lorazepam.
