In most cases, patients present with a deformity in the femoral head, or acetabulum, a poorly positioned femoral-acetabular junction, or any or all of the foregoing. The cause of FAI is currently unknown, but both congenital and acquired etiologies have been put forth. Studies have shown an increased incidence in siblings, suggesting a genetic component. At least one study has also shown a predilection in the white population. It has also been reported to be more common in males. However, there is no concrete evidence to suggest a genetic trait and instead, the most favored theory currently supports that FAI (the cam type in particular) is due to repetitive movements involving the hip (e.g. squatting) in young athletes. Aggravating activities that are commonly reported include repetitive or prolonged squatting, twisting movements of the hip, like pivoting during athletics, getting in and out of cars, and even sitting for prolonged periods. A combination of these factors may also predispose to a form of FAI; predominantly, a marginal developmental hip abnormality together with environmental factors such as recurrent motion of the legs within a supraphysiologic range.Three types of FAI are recognized (see title image). The first involves an excess of bone along the upper surface of the femoral head, known as a cam deformity (abbreviation for camshaft, which the shape of the femoral head and neck resembles). The second is due to an excess of growth of the upper lip of the acetabular cup and is known as a pincer deformity.
Damage to brain functioning could be due not only to organic (physical) injury (a severe blow to the head, stroke, chemical and toxic exposures, organic brain disease, substance use, etc.) and also to non-organic means such as severe deprivation, abuse, neglect, and severe psychological trauma. Symptoms
Many of the symptoms of Organic Mental Disorder depend on the cause of the disorder, but are similar and include physical or behavioral elements. Dementia and delirium are the cause of the confusion, orientation, cognition or alertness impairment. Therefore, these symptoms require more attention because hallucinations, delusions, amnesia, and personality changes are the result. These effects of the dementia and delirium are not joined with the changes of sensory or perception abilities. Memory impairment, judgment, logical function and agitation are also some extremely common symptoms. The more common symptoms of OBS are confusion; impairment of memory, judgment, and intellectual function;  and agitation. Often these symptoms are attributed to psychiatric illness, which causes a difficulty in diagnosis. Associated conditions
Disorders that are related to injury or damage to the brain and contribute to OBS include, but are not limited to:

Alcoholism
Alzheimers disease
Attention deficit/hyperactivity disorder
Autism
Concussion
Encephalitis
Epilepsy
Fetal alcohol syndrome
Hypoxia
Parkinsons disease
Intoxication/overdose caused by substance use disorders including alcohol use disorder
Non-medical use of sedative hypnotics
Intracranial hemorrhage/trauma
Korsakoff syndrome
Mastocytosis
Meningitis
Psychoorganic syndrome
Stroke/transient ischemic attack (TIA)
Withdrawal from drugs, especially sedative hypnotics, e.g. alcohol or benzodiazepinesOther conditions that may be related to organic brain syndrome include: clinical depression, neuroses, and psychoses, which may occur simultaneously with the OBS.
