Abstract: A method for predicting the likelihood of developing ASD and ASD-related diseases in a subject is disclosed. The method includes the steps of measuring the level of homocysteine, a homocysteine precursor or a homocysteine metabolite in the subject and evaluating the likelihood of developing ASD and ASD-related diseases based on the result of measurement. A subject is deemed to have a high risk of developing ASD and ASD-related diseases if the level of homocysteine, the homocysteine precursor or the homocysteine metabolite in the subject is at or below a threshold level. Also disclosed are a composition for reducing the risk of developing ASD, ASD-related diseases and adult neurological abnormalities and a method for determining a vaccination schedule in a subject.

Abstract: A test administration center is provided at which a plurality of balance diagnostic tests are administered on a patient. A test evaluation center, located remotely from the test administration center, is provided at which diagnostic data is evaluated by a skilled clinician. A computer network links, and transfers data from, the test administration center to both the test evaluation center, where the data is evaluated, and to a patient database, where the data is stored.

Abstract: The invention provides standardized guidelines for diagnosis and treatment of central nervous system abnormalities such as concussions, head trauma, memory loss, confusion, or other cognitive dysfunction. An initial assessment is made of the person for loss of consciousness, spinal cord injury, or a secondary injury. The person is asked to perform a plurality of mental and physical exercises. A dynamic visual acuity test is also taken. These tests can be performed on the sideline of an athletic playing field to determine whether or not it is advisable for an athlete to return to play. Next, machine-based hearing, dynamic-vision, and balance tests are administered to the patient. The results of these machine-based tests are transmitted electronically to an online database and evaluated by a physician at an off-site location, who prescribes a treatment regimen designed to improve the patient's vestibular functioning.
