Ganser’s syndrome
Published in David Enoch, Basant K. Puri, Hadrian Ball, Uncommon Psychiatric Syndromes, 2020
David Enoch, Basant K. Puri, Hadrian Ball
On admission he appeared to be an old-looking man of 55 years, though well built and well nourished. Apart from brisk reflexes in both lower limbs and limitation of straight-leg raising, more so on the right side, no abnormal physical signs were detected. He was obviously perplexed, anxious, confused and appeared to be in pain. He was not then hallucinated but stated that he had heard voices a month ago. He showed poverty of speech, limited spontaneity and considerable sensorial impairment. He was disorientated for time and place. On being asked what month it was (December) he answered, “November.” On being asked what place he was in, he answered “I forget where I am at times.” Attention and concentration were poor. Asked to subtract serial sevens from one hundred, he gave the answers: 100 – 7 = 83; 83 – 7 = 76; 76 – 7 = 63; 63 – 7 = 46. There was obviously a patchy memory loss present which seemed to confirm his assertion that he forgot things. He was particularly vague about the circumstances of his marriage which had occurred only two months previously. It was noted that he answered questions with great deliberation and took them very seriously.

He seems irritable and it is difficult to establish a rapport. His speech is coherent, relevant but slow. He displays psychomotor retardation. He does not have formal thought disorder or any other psychotic symptoms. His mood appears labile varying from low to mildly euphoric and irritable. He is orientated in time, place and person. His attention span and concentration are impaired as evidenced by serial sevens test. When asked to name words beginning with the letter ‘F’, he names six words in 1 minute (normal range 10–20 seconds) indicating impaired verbal fluency. He is unable to perform reciprocal tasks (tapping once when the examiner taps twice and tapping twice when the examiner taps once) or alternating tasks (alternately drawing triangles and rectangles).

A modified version of the original Serial Sevens Test was used to assess cognitive function on PRE and POST (Hayman 1942). The Serial Subtraction Test (SST) consisted of a 2 min timed test in which participants were provided a sheet of paper with a list of subtraction equations. Participants were required to subtract the number seven from each random computer-generated four digit number to measure how quickly and accurately they can compute simple mathematical problems. Participants were asked to complete as many calculations as possible in the 2 min period. The number of correct answers was recorded. The test was conducted in a quiet room with no distractions. Participants were familiarized with this test on FAM day by completing one 2 min round.

Participants also performed an abbreviated version of the NeurCom SOT, this time incorporating a cognitive function task. Participants performed one 20-s trial for each of the six conditions while also performing serial sevens (i.e. verbally counting backwards by seven from a three-digit number). Once again, an equilibrium score was calculated for each of the six conditions in order to quantify postural stability during the SOT while performing the serial sevens task. As mentioned previously, higher equilibrium scores suggest increased postural stability.
Hand and torso pre-cooling does not enhance subsequent high-intensity cycling or cognitive performance in heat

Importantly, the Serial Sevens task is a complex cognitive test that assesses attention, working memory maintenance and manipulation [38]. By maintaining or improving working memory capacity (as seen here), it would be expected that attention would be improved, thus enhancing the ability to block out distractions during sporting events [28]. The comparable cognitive scores found between all trials here is most likely a reflection of the similar Tc values recorded at the end of pre-cooling.
