Combined delusional misidentification syndrome in a patient with Parkinson's disease.
TLDR
A patient with advanced PD and combined Capgras and intermetamorphosis syndromes for whom known predisposing factors appear to be insufficient to explain DMS in PD is described.
Delusional misidentification in Parkinson’s disease: report of two cases and a review
TLDR
Two cases of Parkinson’s disease with an unusual delusional misidentification, intermetamorphosis, are presented, along with their improvement with pimavanserin, a novel atypical antipsychotic medication.
Behavioral effects of levodopa

TLDR
Appropriate management remains challenging, because reduction of levodopa (l‐dopa) and dopaminergic treatment is often recommended; however, doses required for control of motor symptoms may still induce behavioral changes.
Parkinson's disease psychosis: presentation, diagnosis and management.
TLDR
The initial management approach should focus on identification and treatment of any contributory medical factors, reduction or discontinuation of medications with potential to induce or worsen psychosis, nonpharmacological strategies and consideration of acetylcholinesterase inhibitor treatment in the setting of dementia.
Neuro-Behçet syndrome.
The spectrum of nervous system involvement in Behçet’s syndrome and its differential diagnosis
Behçet’s Syndrome (BS) is a multi-system, vascular-inflammatory disease of unknown origin, involving the nervous system in a subgroup of patients. The growing clinical and imaging evidence suggests…
Hallucinations and the spectrum of psychosis in Parkinson's disease
Psychosis and Parkinson’s Disease
TLDR
Effective and well-studied treatments that improve Parkinson’s disease psychosis without worsening motor function are still needed.
Psychotic symptoms in Parkinson’s disease: Etiology, prevalence and treatment
TLDR
An evidence-based review on the etiology, prevalence and management of psychotic symptoms in Parkinson?s disease is provided and a complex interrelationship of factors associated with the disease itself and the factors associated with antiparkinsonian medications is suggested.
An update expert opinion on management and research strategies in Parkinson's disease psychosis
TLDR
Novel research strategies focus on nondopaminergic systems and incorporate neuroimaging, genetic associations and animal models and have the potential to enhance understanding of PD psychosis and advance the development of agents that can ultimately be tested in well-designed, randomized, controlled trials.

Fregoli syndrome.

  • 1994
TLDR
The author presents a review of 34 cases of Fregoli syndrome in the English and French language literature, discussing the syndrome's definition, aetiology and course and suggested that although an organic substrate may be found in some cases, it is the dominant psychotic theme which determines the content of the syndrome.
Frégoli syndrome after cerebral infarction.
TLDR
A case of a rare form of delusional misidentification, the Frégoli syndrome, is described and a diagnosis of paranoia (delusional disorder) secondary to predominantly right hemisphere pathology, rather than schizophrenia, seemed more appropriate.
Delusional misidentification in association with parkinsonism.
TLDR
Three cases of DMS in patients with Parkinson's disease and dementia, treated with dopaminergic medications, are presented and it is postulated that DMS associated with parkinsonism results from a combination of dopaminaergic psychosis and cognitive dysfunction involving the frontal lobe in particular.
Capgras syndrome in Parkinson's disease
TLDR
The Capgras syndrome is characterized by the delusional belief that a person close to the patient has been replaced with one or more impostors, but it is rare to see this type of delusional misidentification syndrome persistently in Parkinson’s disease.
A possible variant of neuro-Behçet disease presenting chronic progressive ataxia without mucocutaneo-ocular symptoms
TLDR
Clinical, radiological, and neuropathological findings for two patients with a possible variant of NBD, who manifested progressive ataxia in the absence of mucocutaneo-ocular signs characteristic for BD are described.
[A case of neuro-Behçet's disease presenting as chronic progressive cerebellar ataxia].
TLDR
The existence of a new subtype of neuro-Behçet's disease characterized by chronic progressive cerebellar involvement possibly due to microvasculitis for which corticosteroids may be effective is proposed.
Thalidomide in the Treatment of the Mucocutaneous Lesions of the Behcet Syndrome
TLDR
Whether thalidomide is effective for treatment of the mucocutaneous lesions of the Behcet syndrome and can prevent the development of new oral and genital ulcers is determined.
Central nervous system manifestations of rheumatologic diseases
TLDR
A better understanding of the clinical, radiographic, and serologic characteristics of various central nervous system complications of rheumatologic diseases has been gained in the past year.
Visual processing in patients with Frégoli syndrome.
TLDR
Performance on the recognition memory test failed to discriminate between the two psychotic groups on the basis of facial recognition, however, the patients with Frégoli delusion failed to show the right hemisphere processing advantage for the animate class of stimuli found for the set of norms and also present in the psychotic control group.
Psychiatric, neurological and medical aspects of misidentification syndromes: a review of 260 cases.
TLDR
The patients with reduplicative paramnesia more frequently suffered from head trauma or cerebral infarction and showed more features of right hemisphere lesions on neuropsychological testing or CT scan than the patients with other misidentification syndromes.
