Hypertensions and lacunar infarcts and lacunar stroke are related. For exclusion of haemorrhagic or lacunar strokes CT or MRI imaging is needed. Lipohyalinosis was considered the most common cause for lacunar infarcts. Occupational therapy and physical therapy interventions are used in the rehabilitation of lacunar stroke. It may manifest as lacunar and/or hemorrhagic strokes, cutaneous lesions or polyarteritis nodosa. With TJ Chambers he developed the osteoclast lacunar bone resorption assay system. Each of the five classical lacunar syndromes has a relatively distinct symptom complex. Blockage of the lenticulostriate arteries causes lacunar infarcts. These types of strokes include lacunar and other ischemic strokes and minor hemorrhages. Approximately 10% of these silent strokes are silent lacunar infarctions. Lacunar amnesia is the loss of memory about a specific event. Lacunar amnesia is the loss of memory about one specific event. Lacunar infarcts are a result of atherosclerosis (microthrombi) and lipohyalinosis. The lacunar ligament can be a site of entrapment for femoral hernias. The access to the central room is through an inward opening two-winged lacunar stone door.
