Effects of Hormone Replacement Therapy on Cognitive Aging: Women's Health Initiative Study of Cognitive Aging (WHISCA)
The Women's Health Initiative Study of Cognitive Aging (WHISCA) is a two-armed, randomized,
placebo controlled, clinical trial designed to assess the efficacy of postmenopausal hormone
therapy (HT) on age related changes in specific cognitive functions.
placebo controlled, clinical trial designed to assess the efficacy of postmenopausal hormone
therapy (HT) on age related changes in specific cognitive functions.
WHISCA is an ancillary study to the Women's Health Initiative (WHI) and the WHI Memory Study
(WHIMS) and has enrolled 2303 women aged 66 to 84 years who did not meet the criteria for
dementia. WHISCA is investigating the effects of hormone therapy on rates of change over time
in memory, other aspects of cognition (language, attention, spatial ability), motor function,
and mood.
Objectives
- Does HT protect against age-associated memory and cognitive longitudinal decline in
women age 65 and older?
- What is the rate of change in memory and other cognitive abilities in women receiving HT
compared to women receiving placebo?
- Does the addition of progesterone to HT modify the effects of estrogen on memory and
other cognitive abilities?
