“…Ouyang et al suggest that emotional stress can produce glutamate in the corticolimbic tract [ 1 ]. Therefore, hyper-glutaminergic transmission in the frontal lobe may cause dissociative symptoms in GS [ 18 ]. Kroll et al postulated that damage to the prefrontal cortex which accounts for confabulation and autobiographical amnesia may result in GS [ 19 ].…”

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 shortterm 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.

“…There are reports of Ganser's syndrome secondary to hemorrhage in the temporo-parietal lobe. 7 There are also evidences in literature to support both organic and hysterical reasons for Ganser's syndrome. In our patient the intracranial space occupying lesion in the frontotemporoparietal region was completely resected, which resulted in complete resolution of the symptoms.…”

“…Ganser's syndrome has also been associated with various other functional psychiatric disorders and organic states. 7 This condition is also seen secondary to stroke and head injury, predominantly affecting the frontal lobes.

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.

“…There are few case reports from India showing the finding of approximate answers. [ 2 3 4 5 ] Controversy is centered around the diagnosis and malingering is a very close differential for it. Here, the authors report a case in a nonprison setting which also illustrates the diagnostic difficulty in between the two, especially in view of constraints in terms of changing clinical pictures, noncooperation of patient for detailed psychological assessments and informants.…”
