Postmenopausal confusion refers to a perceived reduction in cognitive capacity associated with the Menopauseplugin-autotooltip__plain plugin-autotooltip_bigMenopause

The decline in the number viable ovarian follicles, which leads to the menopause, is well documented (see Wikipedia), but, from an evolutionary perspective the reasons for its prevalence in humans are unknown.

Only a few other mammals* are known to exhibit menopause - including orcas, short-finned pilot whales and chimpanzees..

It's thought to affect as many as 60% of the postmenopausal population worldwide (i.e. more than a billion people). The symptoms are poorly defined, but include forgetfulness, difficulty concentrating, difficulty learning, and so-called 'brain fog'.

Specific causes are unknown, but it's thought likely to be assocated with changing hormone levels. Various 'risk factors' are known to increase the likelihood of it occurring. Including, Hypertensionplugin-autotooltip__plain plugin-autotooltip_bigHypertension

Only 5 -10% of cases of hypertension (high blood pressure) have causes which can be clearly identified - e.g. due to narrowing of the arteries. Put another way, of those patients who have been identified as having abnormally high blood pressure, physicians will not be able to pinpoint a specific cause in more than 90% of cases., Arterial sclerosis (a.k.a Atherosclerosis)plugin-autotooltip__plain plugin-autotooltip_bigArterial sclerosis (a.k.a Atherosclerosis)

Arterial sclerosis (a.k.a. atherosclerosis) is an extremely common condition which can cause coronary thrombosis, myocardial infarction and other serious conditions.

"The exact cause of atherosclerosis isn't known., Insomnia, depression &etc.

The mechanism of postmenopausal confusion is poorly understood due to simultaneous aging-related physiological changes, as well as differential diagnoses presenting with similar symptoms. Research remains ongoing.
