What are the symptoms of a lacunar stroke?

What are the symptoms of a lacunar stroke?

Signs of lacunar stroke can include:

• slurred speech.
• inability to raise one arm.
• drooping on one side of the face.
• numbness, often on only one side of the body.
• difficulty walking or moving your arms.
• confusion.
• memory problems.
• difficulty speaking or understanding spoken language.

What is the most common lacunar stroke syndrome?

There are over 20 lacunar syndromes that have been described, but the most common ones are pure motor hemiparesis, pure sensory stroke, ataxic hemiparesis, sensorimotor stroke, and dysarthria-clumsy hand syndrome.

What is sensory stroke?

Pure sensory stroke (PSS) is a lacunar syndrome affecting various areas of the somatosensory system. PSS is defined as a specific type of stroke displaying prominent hemisensory symptoms without other major neurological deficits.

What is toast stroke?

Results: The TOAST classification denotes five subtypes of ischemic stroke: 1) large-artery atheroscle- rosis, 2) cardioembolism, 3) small-vessel occlusion, 4) stroke of other determined etiology, and 5) stroke of undetermined etiology. Using this rating system, interphysician agreement was very high.

Can you have a lacunar stroke and not know it?

Although doctors do not know the precise cause of lacunar infarctions, they are still thought to be due to disease of the blood vessels. Unlike strokes, lacunar infarctions are often not noticed by patients, though subtle symptoms sometimes can be present (trouble with memory or thinking).

Where does a lacunar stroke occur?

A stroke in a deep area of the brain (for example, a stroke in the thalamus, the basal ganglia or pons) is called a lacunar stroke. These deeper structures receive their blood flow through a unique set of arteries.

What is a thalamic stroke?

A thalamic stroke is a type of lacunar stroke, which refers to a stroke in a deep part of your brain. Thalamic strokes occur in your thalamus, a small but important part of your brain.

What is clumsy hand syndrome?

Dysarthria-clumsy hand syndrome is characterized by the combination of facial weakness, severe dysarthria, and dysphagia, with mild hand weakness and clumsiness. [10, 80] Occasionally, some weakness of the arm or leg is present.

What does Cardioembolic mean?

Introduction. Cardioembolic stroke is defined as the presence of a potential intracardiac source of embolism in the absence of cerebrovascular disease in a patient with nonlacunar stroke. It is responsible for approximately 20% of all ischemic strokes.

What is a stroke subtype?

Stroke is classified into the following subtypes: intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and brain ischemia due to thrombosis, embolism, or systemic hypoperfusion.

Are white matter hyperintensities associated with stroke risk?

White matter hyperintensities are a predictor for vascular disease for which age and high blood pressure are the main risk factors. The review showed that WMHs are significantly associated with an increased risk of stroke.

What are periventricular white matter hyperintensities (WMHs)?

Periventricular White Matter Hyperintensities on a T2 MRI image WHAT IS THE NEUROPATHOLOGY OF WMH’S? WMH’s are associated with vascular risk factors such as diabetes, smoking and hypertension and hence WMH’s are considered part of small vessel disease. Some potential neuropathological associations are:

How does age affect the appearance of white matter hyperintensities on MRI?

Aging is associated with the appearance of increased white spots visualized on brain MRI scans. The presence of these anomalies, called white matter hyperintensities, characterizes elderly subjects as well as ischemic stroke patients, regardless of their age.

Do white matter hyperintensities increase the risk of dementia?

The presence of white matter hyperintensities may increase the risk that an individual will develop mild cognitive impairment or have declining performances on cognitive tests but may not be enough to facilitate progression from mild cognitive impairment to dementia, the latter being overwhelmingly driven by neurodegenerative lesions.
