17] Placental malaria can produce pathological changes in the placenta, such as thickening of the basement membrane, inflammatory cell infiltrates, villitis and microinfarct owing to clumping of parasitised red blood cells and the occlusion of micro vasculatures.
Or, TIA patients may have suffered a microinfarct undetectable via neuroimaging with computed tomography (CAT) or magnetic resonance imaging (MRI).
The finding of even a single microinfarct in a non-diabetic patient is significant.

In addition, vulnerable plaques are more prone to microvascular changes and embolization, causing microinfarcts and silent strokes.
Scattered microinfarcts were present in cerebellum, lateral thalamus, and frontal cortex.
Recent studies indicate that hypertension might potentiate the impact of Alzheimer's disease and its role in causing microbleeds, microinfarcts, white matter disease, and multiple small strokes that might not be clinically noticeable at the time but can lead to dementia, as well as possible involvement in the accumulation of amyloid plaques in the brain (10,11).
Recent research suggests, however, that other pathologies linked with dementia--such as Lewy bodies (abnormal deposits of a protein inside brain cells), hippocampal sclerosis (a severe loss of brain cells in a key memory region called the hippocampus), microinfarcts (small mini-strokes) and low brain weight--are also commonly present in the brains of individuals with dementia.
In Hendra virus-associated encephalitis, MRI shows similar microinfarcts with T2/FLAIR and DWI lesions (9).
38,39) But Alzheimer's disease patients show a higher-than-normal incidence of microinfarcts, independent of the amyloid-beta deposition in their blood vessels.
