A brief review of the literature in relation to time disorder and LSD-25 is given. Twenty nine patients were studied as regards their time experiences under LSD-25. Eight patients reported an altered time experience following the initial administration of the drug. Twelve patients who had not developed a time disturbance in their initial administration, received LSD-25 a second time at increased dosage, 5 of these patients then experienced a time disturbance. There was a tendency for time disorder to be associated with visual perceptual changes and for it to occur in the non-schizophrenics. Time disorder was considered to be a non-specific response. Recent views on the nature and genesis of time disorders are discussed. © 1964 Springer-Verlag.
