A new study by Lancet Psych took a look into 125 hospital patients and their mental states. Through their research 57 have had blood clots in the brain which causes Ischemic Stroke. 39 altered mental states were reported. Also, 10 patients were newly diagnosed with psychosis. It is worth it to note that the people observed in this research were in the hospital, so it looks at the most extreme cases. Half of those with altered mental states were younger than 60.
