The Promise and Demise of LSD Psychotherapy in Norway

Social History of Medicine May 28, 2021 Per Haave, Willy Pedersen 7 citations

Abstract In the early-to-mid 1960s, there was considerable use of LSD in psychotherapy in several countries. However, its use gradually levelled off. Two explanations have been suggested: The first revolves around a ‘moral panic’ in the wake of the introduction of cannabis and LSD by subcultural youth groups. The second focuses on the lack of proof for the therapeutic efficacy of LSD at a time...

We extended the PhilPapers survey to measure a...

Seizure and Interictal Electroencephalographic (EEG) Changes with Cannabinoid Concentrate Use.

The American journal of case reports April 18, 2021 Madeline D Kahan, Andrew G. Breithaupt, Kendall Nash et al.

BACKGROUND The electroencephalographic (EEG) findings associated with tetrahydrocannabinol (THC) use, particularly in concentrated form, are not well-described, despite the current widespread availability of these products.

Unlike "traditional" illicit drugs, very little is known about the influence of their analogs on neuropsychological functioning. We characterized the cognitive and emotional profile of...

Differenzialdiagnostische Unterscheidung zwischen substanzinduzierten und primären Psychosen:

Der Nervenarzt March 3, 2021 Dusan Hirjak, Andreas Meyer‐Lindenberg, Geva A Brandt et al. 8 citations

Zusammenfassung Substanzinduzierte psychotische Störungen (SIPS) sind häufig und für ca. 25 % der ersten Einweisungen in eine psychiatrische Klinik verantwortlich. Aus klinischer Sicht ist aufgrund ähnlicher psychopathologischer Phänomene die diagnostische Unterscheidung zwischen SIPS und primären (genuinen oder kryptogenen) psychotischen Störungen oft eine Herausforderung. Dieser Umstand wird...
