One complication in diagnosis is that symptoms of PCS also occur in people who have no history of head injury, but who have other medical and psychological complaints. [31] In one study 64% of people with TBI, 11% of those with brain injuries, and 7% of those with other injuries met the DSM-IV criteria for post-concussion syndrome. Many of ...
The patients affected most often include young adults and adolescents that are 16 to 19 years old. [40] Adolescents who sustain a head injury that goes unrecognized could be placing themselves at a greater risk due to the effects of longer and more diffuse cerebral swelling that occurs in their body.

Cerebrospinal fluid is produced by the choroid plexus in the ventricles of the brain and contained by the dura and arachnoid layers of the meninges. [23] [42] [64] The brain floats in CSF, which also transports nutrients to the brain and spinal cord. As holes form in the spinal dura mater, CSF leaks out into the surrounding space.
The incidence of symptomatic PAD increases with age, from about 0.3% per year for men aged 40–55 years to about 1% per year for men aged over 75 years. The prevalence of PAD varies considerably depending on how PAD is defined and the age of the population being studied.
The diagnosis is typically made with magnetic resonance imaging of the brain. The findings most characteristic for PRES are symmetrical hyperintensities on T 2-weighed imaging in the parietal and occipital lobes; this pattern is present in more than half of all cases. [1] [3] FLAIR sequences can be better at showing these abnormalities. [4]
In the United States, over 800,000 patients a year are hospitalized because of a fall injury, most often because of a head injury or hip fracture. [43] Motor vehicle crashes are the second most common mechanism of injury among geriatric adults, and the most common cause of traumatic mortality. [44]
Concussion grading systems are sets of criteria used in sports medicine to determine the severity, or grade, of a concussion, the mildest form of traumatic brain injury.At least 16 such systems exist, [1] and there is little agreement among professionals about which is the best to use. [2]
Central cord syndrome (CCS) is the most common form of cervical spinal cord injury (SCI). It is characterized by loss of power and sensation in arms and hands. It usually results from trauma which causes damage to the neck, leading to major injury to the central corticospinal tract of the spinal cord. [1]
