A FORMER top volleyball official charged with false accounting involving more than $157,000 is suffering from senile dementia, a magistrate was told yesterday. But Eastern Court also heard that Shek Chun-tak, 77, might have exaggerated his responses during medical examinations. Dr Barry Connell, a neuropsychologist, called by the defence, told the court he once had suspicions over whether the former president of the Hong Kong and Kowloon Volleyball Association was malingering in order to avoid having to stand trial. But after having conducted several tests, Dr Connell said he was satisfied Shek was suffering from dementia. 'He maybe at times exaggerated in telling people what he ought to tell them. But, as a doctor, my professional duty is to look beyond to what the underlying condition is . . . there is an element of pseudo-dementia,' the doctor said. A neurological surgeon, Fali Shroff, had also examined Shek and told the court the defendant's brain was not functioning normally in all aspects. He said the pictures taken from a magnetic resonance imaging brain scanner showed Shek's brain had degenerated. During cross-examination, prosecutor Jackson Poon said the brain scanner diagnosis did not indicate the degree of Shek's senile dementia. Both doctors agreed with him on this point. Kevin Egan, defending Shek, said the defendant was not fit for trial as a result of his poor physical condition. He said Shek could not do himself justice because he was unable to remember the events as they happened more than 51/2 years ago and he could not respond to specific allegations. Shek is facing five charges of false accounting over allegedly falsified receipts for more than $157,000 in coaching fees between March 1991 and June 1993. He denied the allegations when he was charged in May last year. The trial continues before magistrate James Lee today.
