Kw. Sax et al., COMPARISON OF PATIENTS WITH EARLY-ONSET, TYPICAL-ONSET, AND LATE-ONSET AFFECTIVE PSYCHOSIS, The American journal of psychiatry, 154(9), 1997, pp. 1299-1301
Objective: The authors compared the clinical characteristics and famil
y history of patients with early-onset (before age 18), typical-onset
(dt 20-25 years), and late-onset (after age 35) affective psychosis at
the time of first hospitalization. Method: Diagnostic, symptom and fa
mily history information was obtained from 88 consecutively hospitaliz
ed patients. Results: Major depression was more common in the fate-ons
et group, and a family history of affective and substance abuse disord
ers was more common among the early-onset patients. Affective symptoms
differed significantly among groups; specifically early-onset patient
s had more energy, minimal sleep disruption, and greater suicidality,
while typical-onset patients had move severe abnormal thought content.
Conclusions: Among patients with affective psychosis, there may be he
terogeneity of symptoms and family history associated with age at firs
t hospitalization.
