  • Title: Urinary incontinence in the elderly: the brain factor.
    Author: Griffiths DJ, McCracken PN, Harrison GM, Moore KN.
    Journal: Scand J Urol Nephrol Suppl; 1994; 157():83-8. PubMed ID: 7939456.
    Abstract:
    Recent research has shown that urge incontinence is common in the elderly and is often combined with reduced bladder sensation. It is associated with cognitive impairment and with underperfusion of the frontal lobes of the cortex. To test for an expected preferential association with particular aspects of cognitive function, 47 incontinent patients (25 men and 22 women, median age 78 y) underwent cognitive testing, 24-hour monitoring of bladder function and videourodynamics. Median CAMCOG score was 72/107. Median urine loss in 24 h was 36 g (range 11-1347 g). 17 patients had urodynamic proof of urge incontinence, 8 with normal and 9 with reduced bladder sensation. Impaired orientation in time was more strongly associated with proven urge incontinence than overall cognitive impairment; it was the only significant predictor (P < 0.00005). Praxis, calculation ability, abstract thinking or recent memory were less closely involved. Thus dysfunction of the frontal cortical lobes and impairment of temporal orientation appear to constitute a "brain factor" underlying geriatric urge incontinence, particularly in combination with reduced bladder sensation.
