With aggressive treatment and close monitoring, it is possible to outlive the typical life expectancies for low grade oligodendroglioma. Westergaard's study (1997) showed that patients younger than 20 years had a median survival of 17.5 years.
Multiple system atrophy (MSA) is a rare neurodegenerative disorder [1] characterized by tremors, slow movement, muscle rigidity, postural instability (collectively known as parkinsonism), autonomic dysfunction and ataxia.
CT and MRI are most commonly used to observe the brain for cerebral atrophy. A CT scan takes cross sectional images of the brain using X-rays, while an MRI uses a magnetic field. With both measures, multiple images can be compared to see if there is a loss in brain volume over time. [20]
This damage can include cognitive impairment, behavioral and psychiatric disorders, and various motor impairments. [7] There is, however, not yet any conclusive evidence that AHC is fatal or that it shortens life expectancy, but the relatively recent discovery of the disorder makes large data for this type of information unavailable.
Subdural hygromas require two conditions in order to occur. First, there must be a separation in the layers of the Meninges of the brain. Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
Lissencephaly (/ ˌ l ɪ s. ɛ n ˈ s ɛ f. ə l. i /, meaning 'smooth brain') [1] is a set of rare brain disorders whereby the whole or parts of the surface of the brain appear smooth. [2] It is caused by defective neuronal migration during the 12th to 24th weeks of gestation, resulting in a lack of development of brain folds and grooves . [3]
Despite the reduced brain matter, the man lived a relatively normal life; he was a married civil servant with two kids. He also scored an IQ of 75 which is considered low but not disabled.
The brain can be affected in several ways in this syndrome. Some children are born with structural brain anomalies such as cortical dysplasia or polymicrogyria . While developmental delay is nearly universal in this syndrome it is variable in severity, with the majority having mild to moderate delays and a minority having severe cognitive ...
