Ganser syndrome and lesion in the temporoparietal region

A Rare Case of Ganser Syndrome: Psychogenic or Organic?

Ganser syndrome (GS) is a rare neurological disorder characterized by answer approximation, clouded consciousness, somatic conversion symptoms, and visual or auditory hallucinations. The objective of this case report is to elucidate the presentation of a patient with GS and to highlight the interplay of psychological and organic determinants in this condition.

We present a 66-year-old man with a history of concussion and short-term memory loss who presented with selective, remote, and recent memory loss following the death of his wife, visual hallucinations, approximation of answers regarding his current state, and limited insight into his condition. We found the patient oriented only to place and person, with impaired short-term memory and no language abnormalities. Montreal cognitive assessment (MOCA) exam showed mild-to-moderate cognitive impairment. The patient's presentation can be explained by both psychological and organic causes. Negative results from imaging and testing showed that the patient's recent emotional stressor, the death of his wife, may be contributing to the current state. However, the patient also has a history of hospitalization for traumatic brain injury (TBI) and a recent history of progressive memory loss. Therefore, the combination of psychological and organic factors likely played supplementary roles in the patient's current presentation. This case supports the literature that GS is a psychogenic disorder. However, an organic cause from the long-term sequelae of TBI needs further exploration.

Uncommon and/or bizarre features of dementia

This study aimed at describing uncommon or bizarre symptoms observed in patients suffering from dementia. Medline and Google scholar searches were conducted for relevant articles, chapters, and books published since 1967. Search terms used included uncommon presentation, behavioural and psychological symptoms, dementia, Alzheimer's disease, and fronto-temporal dementia. Publications found through this indexed search were reviewed for further relevant references. The uncommon symptoms are described as case-reports and there are no systematic investigations. Bizarre behaviours arising late in life should be thoroughly investigated as symptoms of dementia.

Conversion, dissociative amnesia, and Ganser syndrome in a case of "chameleon" syndrome: anatomo-functional findings

The term "chameleon" was first used in the seventeenth century by Sydenham to describe a patient with a protean semiology. We report a single case of "chameleon" syndrome that challenges the current international criteria for somatoform disorders, dissociative amnesia, and Ganser syndrome. The florid symptoms were as follows: anterograde and retrograde amnesia (including semantic, episodic, and procedural deficits), loss of identity, atypical neuropsychological impairment (approximate answers), left sensitive and motor deficit, and left pseudochoreoathetosis movement disorders. Additional behavioral disorders included the following: anxiety, clouded consciousness, hallucinations, and "belle indifference". A single photon emission computed tomography examination showed bilateral temporal, frontal and a right caudate (in the head of the caudate nucleus) hypoperfusion concordant with a common mechanism of repression in these disorders.

Intracranial capillary hemangioma mimicking a dissociative disorder

Capillary hemangiomas, hamartomatous proliferation of vascular endothelial cells, are rare in the central nervous system (CNS). Intracranial capillary hemangiomas presenting with reversible behavioral abnormalities and focal neurological deficits have rarely been reported. We report a case of CNS capillary hemangioma presenting with transient focal neurological deficits and behavioral abnormalities mimicking Ganser's syndrome. Patient underwent total excision of the vascular malformation, resulting in complete resolution of his symptoms.

Women psychiatrists in India: A reflection of their contributions

The increasing number of women joining psychiatry is a relatively new phenomenon in the field of medicine. Keeping with the trends world over, the number of women psychiatrists in India has been on the rise over the last two to three decades. The authors searched various volumes of the Indian Journal of Psychiatry, recent membership directories of the Indian Psychiatric Society, website of the Medical Council of India and personal communications for contributions of the women psychiatrists in India. Women psychiatrists have a number of contributions to their credit in India. They have played important roles in the affairs of national professional organizations like the Indian Psychiatric Society and have contributed to the psychiatry education and research. However, they also suffer limitations because of the absence of adequate institutional support and policies looking into their specific needs.
