[Paranoia with late onset. Psychopathology and psychodynamics].

We report on a 70-year-old man who suffered from persecutory delusions during the last 20 years. During first visits, he showed neither cognitive impairment nor Schneiderian first rank symptoms. Inpatient and day clinic treatment as well as further outpatient therapy led to reintegration into social life and trusting relationships between the patient and the therapeutic team, although the persecutory delusions still persisted. During following years, symptoms of cognitive impairment increased gradually and neurological symptoms could be observed. We present a psychodynamic hypothesis regarding the reported psychopathology and discuss alternative diagnoses and pharmacological treatment.
