JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 510 OP 514 DO 10.1136/jnnp.61.5.510 VO 61 IS 5 A1 van Vugt, P A1 Paquier, P A1 Kees, L A1 Cras, P YR 1996 UL http://jnnp.bmj.com/content/61/5/510.abstract AB Increased writing activity in a 70 year old, right handed man presenting with a history of alcohol misuse and maturity onset diabetes is reported. Brain CT disclosed corticosubcortical atrophy and 99mTc-HMPAO SPECT disclosed severe bilateral frontal hypoperfusion more prominent on the right. The patient's neuropsychological symptomatology consisted of severe (verbal) aspontaneity, intermittent utilisation behaviour, and pronounced increased writing activity, which mainly consisted of a perseverative, micrographic written reproduction of visually or verbally perceived language fragments. Several neurological causes of increased writing activity and the equivocal terminology met in the medical literature are reviewed. A distinction between hypergraphia and automatic writing behaviour is proposed. It is concluded that our patient's increased writing activity may be characterised as automatic writing behaviour.
