What are CTE lesions?

What are CTE lesions?

Overview. Chronic traumatic encephalopathy (CTE) is the term used to describe brain degeneration likely caused by repeated head traumas.

What happens in the brain during the progression of CTE?

The brain degeneration is associated with common symptoms of CTE including memory loss, confusion, impaired judgment, impulse control problems, aggression, depression, suicidality, parkinsonism, and eventually progressive dementia.

Why does tau form tangles in CTE patients?

Hyperphosphorylated tau molecules dissociate from microtubules in the axon, translocate to the cell body and proximal dendrites, and aggregate into intracellular inclusions termed neurofibrillary tangles (NFTs), leading to impaired axonal function.

Can you see CTE on a CT scan?

“CTE is not a clinical diagnosis; there are no MRI or CT scans we can order,” says Lorincz, noting that a recent study analyzing spinal fluid to detect CTE has a long way to go before approval and use. “There is no current way to diagnose CTE in a living person, despite what you might hear.”

Does CTE cause anger?

Examples of the breadth of mental health problems attributed to CTE include depression and anxiety (12–14); substance abuse (1, 12, 13); personality changes, anger control problems, and violence (12–14); and suicidal thinking and death by suicide (13–19).

What causes hyperdense lesions on CT scan?

Hyperdense Lesions There are a variety of causes for lesions to be hyperdense (hyperattenuating) on CT scanning. One of the most common causes is hemorrhage, but other etiologies include dense cellularity, mucinous or proteinaceous lesions, and partial or “psammomatous” calcification.

What causes hyper density on CT scan of the brain?

In contrast to typical astrocytic tumors that show hypodense areas on computed tomographic images, some intracranial tumors show hyperdense areas on CT images. The major reasons for hyperdensity on CT images are hypercellular lesions, intratumoral calcification, and intratumoral hemorrhage.

Do hyperdense lesions on brain CT after arterial revascularization in acute ischemic stroke exist?

To analyze the characteristics of hyperdense lesions on brain CT conducted immediately after arterial revascularization (AR) in patients with acute ischemic stroke (AIS), track the outcome of those lesions and investigate their clinical significance. Materials and Methods 97 AIS patients were enrolled in our study.

What causes hyperdense lesions on non-enhanced CT after acute aortic dissection?

Not all hyperdense lesions on non-enhanced CT conducted immediately after AR represent hemorrhage, it may be attributed to either contrast extravasation or cerebral hemorrhage [6, 8].
