“…In these patients confabulation is more often accompanied by euphoria, disinhibition, increased tempo of speech, and expressive speech disturbances (Mansvelt, 1954;Escourolle, 1958;Robertson et al, 1958;Gustafson et al, 1978) while other motor functions remain undamaged. The symptom pattern of reduced speed of motor and intellectual performance, urinary incontinence, and a gait disturbance resembling Bruns' frontal lobe ataxia (Bruns, 1892) had also been connected with frontal predilection of ventricular enlargement (Adams et al, 1965;Benson et al, 1970;Mathew et al, 1975). As seen in Table 4, our patients with hydrocephalic dementia did not have aphasic, agnostic, and apractic disturbances to the same extent as patients with Alzheimer's disease.…”

SUM MARY Twenty-three patients with hydrocephalic dementia were studied before and after shunt operation, and improvement was found in 12. Before operation, the improved cases showed more symptoms of confabulation, gait disturbance, urinary incontinence, lack of insight, and constructional apraxia. The improvement was also most marked in these symptoms. The significance of general versus specific symptoms, duration, and aetiology is discussed from a differential diagnostic standpoint, and we conclude that the adequate and early diagnosis of hydrocephalic dementia is essential for good outcome after shunt operation, and that psychiatric and psychometric evaluation enable such a diagnosis to be made.

“…The results of these investigations show that the PEG and MCS pic tures generally characterizing NPH are for PEG, the lack of air in the ce rebral sulci and, for MCS, an inversion of the isotope circulation in the CSF, with ventricular invasion and/or delayed clearance of the ventricular/subarachnoid spaces [2,3,6,9,12,14,19,24], However, not all the patients regarded as normotensive hydrocephalic, on the basis of the asso ciation of the clinical, PEG and MCS findings as described above, im prove following CSF surgical shunting. The results of recent researches appear to indicate that further useful information for a correct diagnosis and for surgical prognosis can be obtained from a detailed study of the CSF pressure behaviour [15-18, 25, 27, 28[.…”

Cerebrospinal Fluid Pressure Studies in Normal Pressure Hydrocephalus and Cerebral Atrophy

The surgical results obtained with a cerebrospinal fluid (CSF) shunt operation in 13 patients considered to be suffering from normal pressure hydrocephalus have been correlated with the findings of the constant manometric infusion test (IT) and of prolonged intracranial pressure recordings. A positive IT, high amplitude CSF pulse pressure and large transitory increases of CSF pressure during sleep seem to be useful criteria for the surgical prognosis. Ten more patients affected by primary cerebral atrophy have also been studied. The data obtained in both groups of patients have been utilized for a possible pathogenetic interpretation of the syndrome.

“…In the present cases the diagnosis of MD was made by conventional criteria [7], The CT scans and the clinical history in both patients fulfill the criteria for a diagnosis of normal pressure hydrocephalus used by others [3,4]. In 1 patient this diagnosis was confirmed by intraven tricular pressure monitoring, including an infusion test.…”

Normal Pressure Hydrocephalus in Myotonic Dystrophy

Two elderly siblings with myotonic dystrophy (MD) were admitted with symptoms and signs of normal pressure hydrocephalus, the diagnosis being confirmed by CT scan and infusion test. A further 11 younger members of the family also had MD; in 2 of these, none of whom had cerebral symptoms, CT scan showed cerebral ventricular enlargement. Based on these findings, together with earlier reports on progressive cerebral ventricular enlargement in patients with MD, it is suggested that in some cases normal pressure hydrocephalus may be a late complication of MD.
