Summary
Mild cognitive impairment is common in acute lacunar infarction patients. Atypical lacunar syndrome and pure motor hemiparesis subtypes showed more executive disturbances, impacting neuropsychological function.
Area of Science:
- Neurology
- Neuropsychology
- Vascular Neurology
Background:
- Lacunar infarction, a common stroke type, can lead to cognitive deficits.
- Neuropsychological abnormalities in acute lacunar infarction require further investigation.
Purpose of the Study:
- To assess neuropsychological abnormalities in patients with acute lacunar infarction.
- To correlate infarction topography, infarct burden, and white matter hyperintensities with neuropsychological test results and lacunar infarction subtypes.
Main Methods:
- Neuropsychological tests were administered to 40 patients within 1 month post-stroke.
- Infarction characteristics (location, silent infarcts, white matter hyperintensities) were analyzed.
- Patients were categorized by lacunar infarction subtypes (pure motor, pure sensory, etc.).
Main Results:
- 57.5% of patients exhibited mild neuropsychological disturbances.
- Atypical lacunar syndrome and pure motor hemiparesis were associated with significantly more executive dysfunction.
- Patients with dysarthria-clumsy hand/ataxic hemiparesis performed better on visuoconstructive and visual memory tasks.
Conclusions:
- Mild neuropsychological impairment is a frequent clinical feature in acute lacunar infarction.
- Specific lacunar infarction subtypes, particularly atypical lacunar syndrome and pure motor hemiparesis, are linked to greater cognitive deficits.
- Consideration of neuropsychological deficits is crucial for managing patients with acute lacunar infarction.

01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
