As such, autopsy series have estimated the prevalence between 5% and 86%. The largest autopsy report, which included 1056 subjects, found a prevalence of 26%, 88% of which involved the LAD.
The largest risks for PTS are having an altered level of consciousness for a protracted time after the injury, severe injuries with focal lesions, and fractures. [8] The single largest risk for PTS is penetrating head trauma , which carries a 35 to 50% risk of seizures within 15 years. [2] If a fragment of metal remains within the skull after injury, the risk of both early and late PTS may be increased. [5] Head trauma survivors who abused alcohol before the injury are also at higher risk for developing seizures. [4] Occurrence of seizures varies widely even among people with similar injuries. [5] It is not known whether genetics play a role in PTS risk. [11] Studies have had conflicting results with regard to the question of whether people with PTS are more likely to have family members with seizures, which would suggest a genetic role in PTS. [11] Most studies have found that epilepsy in family members does not significantly increase the risk of PTS. [5] People with the ApoE-ε4 allele may also be at higher risk for late PTS. [1] Risks for late PTS include hydrocephalus , reduced blood flow to the temporal lobes of the brain, [1] brain contusions , subdural hematomas , [5] a torn dura mater , and focal neurological deficits . [9] PTA that lasts for longer than 24 hours after the injury is a risk factor for both early and late PTS. [1] Up to 86% of people who have one late post-traumatic seizure have another within two years.

In the 10 years from 1925 and 1935, 89 people and thousands of livestock had died from it—“the highest human mortality from rabies-infected bats thus far recorded anywhere.” [4] In 1931, Dr.

Parkinson et al. (2001) found that women with active acromegaly had serum IGF1 values 82 ng/ml less than males (P less than 0.02) for a given serum GH value.
Eight of these 11 mutation carriers were found to carry 11 lesions suggestive of cranial meningioma and 6 spinal lesions consistent with meningiomas or schwannomas. Nine (82%) of the 11 cranial meningiomas were found in the falx cerebri.
Familial multiple meningioma is a rare, benign neoplasm of the central nervous system characterized by the development of multiple or, rarely, solitary meningiomas in two or more blood relatives, without other apparent syndromic manifestations. Depending on the localization, growth rate and size of the tumors, patients can present with subtle, gradually worsening or abrupt and severe neurological compromise or can be completely asymptomatic.
Fonknechten et al. (2000) analyzed DNA from 87 unrelated patients with autosomal dominant hereditary spastic paraplegia and detected 34 novel mutations scattered along the coding region of the SPG4 gene.
Spastic paraplegia type 4 (also known as SPG4) is the most common of a group of genetic disorders known as hereditary spastic paraplegias. These disorders are characterized by progressive muscle stiffness (spasticity) in the legs and difficulty walking. Hereditary spastic paraplegias are divided into two types: pure and complex. The pure types generally involve only spasticity of the lower limbs and walking difficulties. The complex types involve more widespread problems with the nervous system; the structure or functioning of the brain; and the nerves connecting the brain and spinal cord to muscles and sensory cells that detect sensations such as touch, pain, heat, and sound (the peripheral nervous system).
Spastic paraplegia 4 (SPG4) is the most common type of hereditary spastic paraplegia (HSP) inherited in an autosomal dominant manner. Disease onset ranges from infancy to older adulthood. SPG4 is characterized by slowly progressive muscle weakness and spasticity (stiff or rigid muscles) in the lower half of the body. In rare cases, individuals may have a more complex form with seizures, ataxia, and dementia. SPG4 is caused by mutations in the SPAST gene. Severity of symptoms usually worsens over time, however some individuals remain mildly affected throughout their lives. Medications, such as antispastic drugs and physical therapy may aid in stretching spastic muscles and preventing contractures (fixed tightening of muscles).
A rare form of hereditary spastic paraplegia with high intrafamilial clinical variability, characterized in most cases as a pure phenotype with an adult onset (mainly the 3rd to 5th decade of life, but that can present at any age) of progressive gait impairment due to bilateral lower-limb spasticity and weakness as well as very mild proximal weakness and urinary urgency. In some cases, a complex phenotype is also reported with additional manifestations including cognitive impairment, cerebellar ataxia, epilepsy and neuropathy. A faster disease progression is noted in patients with a later age of onset.
