Hello ragnar1 Welcome to HCM Chronic hypertensive conditions and transient ischaemic attacks cause micro hemorrhages which are manifesting on MR imaging as microvascular changes. This results in development of multi infarct dementia. Multi infarct dementia is responsible for her symptomatology of short term memory loss, nominal difficulty, reduced ability to concentrate, inability to register and recall new memories. And multi infarct dementia is a reversible condition, once blood supply is regained to affected ares either by development of collaterals of blood vessels or by revascularization. But the condition shouldn t be ignored as it may lead to persistent dementia changes. Controll of hypertension is must in management. Other what can be done is introduction of Omega 3 Fatty Acid Supplements, Multivitamin preparations and cognitive enhancers (like Memantin, Donepezil) in her drug therapy. Hope I cleared your doubt. Thanks take care.
