[Cycloid psychoses as atypical manic-depressive disorders. Results of a family study].

Background: Whereas a growing body of evidence suggests that cycloid psychoses have to be separated from schizophrenic psychoses, their relations to bipolar affective disorder are less clear.

Patients And Methods: In a controlled family study, we recruited 46 patients with cycloid psychosis (CP), 33 with manic-depressive illness (MDI), and 27 controls. Three hundred fifty-six of 389 living first-degree relatives were personally examined by experienced psychiatrists blinded to the diagnosis of the index proband.

Cycloid psychoses are not part of a bipolar affective spectrum: results of a controlled family study.

Background: Whereas a growing body of evidence suggests that cycloid psychoses have to be separated from schizophrenic psychoses, their relations to bipolar affective disorder are less clear. To further clarify this issue a controlled family study was undertaken.

Methods: All living and traceable adult first-degree relatives of 45 cycloid psychotic, 32 manic-depressive and 27 control probands were personally examined by an experienced psychiatrist blind to the diagnosis of the index proband.

Differences in quality of life and course of illness between cycloid and schizophrenic psychoses - a comparative study.

Objective: Cycloid psychoses represent a nosological entity not adequately recognised by contemporary psychiatry. They present with full recoveries after each psychotic episode and, thus, have a favourable prognosis.

Method: To verify this clinical observation course, outcome and quality of life (QoL, measured by the German version of the Lancashire Quality of Life Profile) of 33 patients with cycloid psychosis and 44 schizophrenics were compared after a mean time of 13 years since first hospitalisation.

[Comparative study of life quality in patients with cycloid and schizophrenic psychoses].

Background: Cycloid psychoses represent a nosological entity not adequately recognised by contemporary psychiatry. They show full recovery after each episode and thus have a favourable prognosis.

Methods: Course, psychiatric status, social function, and quality of life (QoL) of 33 patients with cycloid psychosis and 44 schizophrenics were compared (CGI, PANSS, GAF, Strauss-Carpenter,WHOQOL-BREF).

[Autistic hebephrenia: concepts and findings].

The concept of hebephrenia according to Kleist and Leonhard describes distinct clinical entities with a chronically progressive course leading to residual syndroms with a clear cut symptom constellation which is stable over time. The main symptom is a specific kind of pathological affectivity resulting in a lack of profound future- orientated tension. In six case-reports we illustrate the characteristical clinical picture of the autistic hebephrenia, one of the four subforms of hebephrenic psychoses according to Leonhard.
