RESUMO
Despite being an infrequent crime, parental homicide has been associated with schizophrenia spectrum disorders in adult perpetrators and a history of child abuse and family violence in adolescent perpetrators. Among severe psychiatric disorders there is initial evidence that delusional misidentification might also play a role in parricide. Parricides are often committed with undue violence and may result in overkill. The authors present the case of an adult male affected by schizoaffective disorder and Capgras syndrome who committed patricide. Forensic pathologists classify such cases as overkill by multiple fatal means comprising stabbing, blunt trauma and choking. Accurate crime scene investigations coupled with psychiatric examinations of perpetrator allow reconstruction of the murder stages. This overkill case is discussed in the context of a broad review of the literature.

The Capgras syndrome (CS) is a rare psychiatric disorder. CS is classified as a delusional misidentification syndrome. Initially, CS was described in paranoid schizophrenia and schizoaffective disorders. CS has also been reported in neurodegenerative diseases such as Alzheimer's disease and Lewy body dementia. To date, there are very few descriptions of the occurrence of CS in idiopathic Parkinson's disease (PD), with or without dementia. Considering the recent observation of two new cases in PD patients, a systematic overview of the literature published between 1976 and 2016 reporting CS in PD was conducted. The purpose of this article is to examine the phenomenon in people with PD with and without dementia, the psychopathologic context in which it happened, the role played by the dopaminergic medications and to define useful therapeutic strategies. Our CS cases occurred in two elderly patients with advanced PD and cognitive impairment, respectively, after an acute stressor event and after an increase of the total daily dose of levodopa. In light of our observations and the cases reported in the literature, we argue that CS is an acute or subacute psychotic disorder occurring mostly in PD with dementia. Besides, the increase in brain dopamine levels induced by acute stressful events and/or dopamine-enhancing medications should be considered as a possible causal mechanism of CS in patients with advanced stages of PD and cognitive decline.

BACKGROUND: Capgras delusion (CD) has multiple etiologies including neurodegenerative disorders and can be associated with violent behavior. CD is a common complication of Alzheimer dementia (AD); however, CD with violent behavior is uncommon in AD. We report escalating violent behavior by a patient with advanced AD and CD who presented to the emergency department (ED) and required admission to an academic medical center. METHODS: Case analysis with PubMed literature review. RESULTS: A 75-year-old male with a 13-year history of progressive AD, asymptomatic bipolar disorder, chronic kidney disease, hypertension, hyperlipidemia, and benign prostatic hypertrophy presented to the ED with recurrent/escalating violence toward his wife, whom he considered an impostor. His psychotropic regimen included potentially inappropriate medications (PIMs) for geriatric/AD patients-topiramate/amitriptyline/chlordiazepoxide/olanzapine-that are associated with delirium, cognitive decline, dementia, and mortality. Renal dosing for topiramate, reduction in PIMs/anticholinergic burden, and substituting haloperidol for olanzapine resolved his violent behavior and CD. CONCLUSIONS: CD in AD is a risk factor for violent behavior. As the geriatric population in the United States grows, CD in patients with AD may present more frequently in the ED, requiring proper treatment. Pharmacovigilance is necessary to minimize PIMs in geriatric/AD patients. Clinicians and other caregivers require further education to appropriately address CD in AD.

Capgras syndrome, the delusion that identical-appearing impostors have replaced familiar people, is an unusual phenomenon usually seen in schizophrenia or dementia. We recently cared for a 78 year old man who seemed to develop Capgras syndrome as an adverse reaction to diazepam. An iatrogenic cause should be considered in the differential diagnosis of any new delusion, including Capgras syndrome.

The delusional misidentification syndrome (DMS) has been associated with a range of neurological conditions. Three cases of DMS in patients with Parkinson's disease and dementia, treated with dopaminergic medications, are presented. It is postulated that DMS associated with parkinsonism results from a combination of dopaminergic psychosis and cognitive dysfunction involving the frontal lobe in particular. DMS in the setting of parkinsonism may be more frequent than commonly supposed.

Capgras syndrome in association with lithium toxicity is described in a 74-year-old woman. Lithium toxicity should be considered when new delusions occur during lithium therapy.

We have described a patient in whom EEG abnormalities, a seizure disorder, and Capgras syndrome developed two weeks after she started taking disulfiram. That disulfiram has been shown to inhibit dopamine beta-hydroxylase in vitro suggests an etiologic role for dopaminergic pathways in at least some cases of Capgras syndrome. Our experience with this patient suggests that convulsions and psychosis may occur as a side effect of standard dosages of disulfiram in patients with no previous history of psychosis or brain disease. Furthermore, the symptoms may resolve spontaneously without the long-term use of antipsychotic or anticonvulsant medication.
