Analysis of information sources in references of the Wikipedia article "Caudate nucleus" in English language version.
The occurrence of stroke involving only the caudate nucleus seems overall rather uncommon. In one register study 23, it was reported that patients with caudate stroke constituted only 1% of a total number of 3050 stroke patients (2450 ischaemic stroke and 600 haemorrhagic stroke). In the present study, at least nine of the 925 patients initially included in the investigation had lesions involving an area in the superior part of the body of the left caudate nucleus and the adjacent corona radiata.
Clinical diagnosis of subcortical infarction, chiefly lacunar stroke, [...] Subcortical infarction is unfortunately often considered synonymous with lacunar stroke, [...] Not all subcortical strokes are lacunes. The large striatocapsular infarct, even though confined to subcortical structures, usually does give cortical signs [3,4]. The smaller restricted striatocapsular infarct, also due to embolism as is the larger variety, usually does not give cortical signs and is an underacknowledged entity [5,6]. There are other subcortical strokes, including internal borderzone (watershed) infarction, considered most likely due to hypoperfusion and others with even less certain patho-etiologies (TABLE 1) [5,7].
Lacunar infarcts show a paradoxical clinical course with a favorable prognosis in the short term, characterized by a low early mortality and reduced functional disability on hospital discharge, but with an increased risk of death, stroke recurrence and dementia in the mid- and long term. Asymptomatic progression of small-vessel disease is a typical feature of the lacunar infarcts. For this reason, lacunar infarction should be regarded as a potentially severe condition rather than a relatively benign disorder and, therefore, lacunar stroke patients require adequate and rigorous management and follow-up.
Recent studies have shown that the prognosis after lacunar infarcts is not benign; the risk of recurrent stroke is no lower than for other ischaemic stroke subtypes, and there is an increased risk for cognitive decline, dementia and death in the long term.
[Lacunar] infarcts have commonly been regarded as benign vascular lesions with a favourable long-term prognosis. However, recent studies have shown that this is only the case early in the disease course. A few years after infarct, there is an increased risk of death, mainly from cardiovascular causes. The risk of recurrent stroke after lacunar infarct is similar to that for most other types of stroke, and patients have an increased risk of developing cognitive decline and dementia.

In a follow-up study, patients with lacunar infarcts are diagnosed with dementia 4 to 12 times more frequently than the average population.[15] Post-stroke dementia in accumulated lacunar infarct is common despite their small size and association with small vessel disease.[16] [...] Lacunar strokes are a common cause of vascular dementia and mild cognitive impairment, often overlooked in clinical practice. Multiple silent lacunar strokes are documented on brain MRI, with patients presenting with mild cognitive impairment and early dementia.[32]
