What is subcortical ischemia?

What is subcortical ischemia?

Subcortical ischemic depression refers to vascular depression specifically due to lesions and restricted blood flow, known as ischemia, in certain parts of the brain. However, the disorder is typically described as vascular depression in the literature.

What is subcortical small vessel disease?

Subcortical small vessel disease (SVD) leads to lacunar infarcts and progressive damage to the white matter. Patients with progressive damage to the white matter, referred to as Binswanger’s disease (BD), constitute a spectrum from pure vascular disease to a mixture with neurodegenerative changes.

What are the symptoms of brain ischemia?

The symptoms of cerebral ischemia include:

• weakness in one arm or leg.
• weakness in one entire side of the body.
• dizziness, vertigo, double vision.
• weakness on both sides of the body.
• difficulty speaking.
• slurred speech.
• loss of coordination.

  Is there evidence of acute small vessel ischemia?

  No evidence of acute ischemia. Incidental cavum vergae. No calvarial fracture or suspicious bony abnormality seen. No other changes. Elsewhere, extensive periventricular and deep white matter hypoattenuation is consistent with chronic small vessel ischemic change. Loading images…

  How does small ischemic vessel disease affect the brain?

  The brain has many small vessels that are responsible for distributing and regulating blood, fluid, and oxygen in the brain. Small ischemic vessel disease occurs when there is damage to either the vessels themselves or the surrounding white brain matter. This damage eventually affects the brain matter, which is diagnosed with an MRI or CT.

  How is white matter related to small vessel ischemic changes?

  Nonspecific white matter, FLAIR hyperintensities in the subcortical left frontal lobe and right corona radiata statistically related to small vessel ischemic changes. Otherwise, unremarkable MRI the brain.

  How is cerebral small vessel disease ( CSVD ) diagnosed?

  Since it is difficult to visualise CSVD pathologies in vivo, the diagnosis of CSVD has relied on imaging findings including white matter hyperintensities, lacunar ischaemic stroke, lacunes, microbleeds, visible perivascular spaces and many haemorrhagic strokes.

  What are the symptoms of small vessel ischemic disease?

  Small vessel ischemic disease is very common in older adults. If left untreated, it can contribute to mental decline, strokes, walking and balance problems, and dementia. Microvascular ischemic disease is also called: small vessel ischemic disease

  What kind of stroke causes cerebral small vessel disease?

  Cerebral small-vessel disease can be visualized on MRI studies as lacunar infarcts, white matter lesions and cerebral microbleeds.

  What are white matter lesions on CT brain scan?

  Ischemic demyelination White matter lesions representing ischemic demyelination have evolved in terms of our understanding of their pathogenesis and potential clinical significance. Low density lesions on CT brain scan, most commonly seen in the periventricular region, also frequently seen in the centrum semiovale, have b …
