Benefits of technology

"The present invention provides a solution to the problem of determining whether an individual has Attention Deficit Hyperactivity Disorder (ADHD) by analyzing the peripheral skin temperature data of a human subject during a predetermined time interval. This method can provide a non-invasive and accurate way to diagnose ADHD."

Problems solved by technology

ADHD is a difficult disorder to diagnose.
ADHD children may experience significant functional problems, such as school difficulties, academic underachievement, poor relationships with family and peers, and low self-esteem.
Adults with ADHD often have a history of losing jobs, impulsive actions, substance abuse, and broken marriages.
However, there is no one objective, independently validated test for ADHD.
Various objective techniques have been proposed but have not yet attained widespread acceptance.

Embodiment Construction

[0029] According to the invention, it has been found that a signature of ADHD is hidden in fluctuation of the temperature of the skin as measured at the extremities such as at a fingertip. It is well known in the art that as person's stress level increases the blood vessels in the body as is evidenced by the fact a person's blood pressure increases as their level of stress increases. As the blood vessels in the body contract, blood flow is restricted. This is most evident in the extremities such as the fingers, because the blood vessels in the extremities are small and furthest from the heart. A direct result of decreased blood flow to the blood vessels in the extremities is a decrease in the peripheral temperature of the extremities. Conversely, as a person's stress level decreases and one relaxes the blood flows also relax and expand causing blood flow to increase. As the blood flow to the vessels in the extremities increases, the peripheral temperature of the extremities increase...

Abstract

A method for determining a threshold value of a parameter used to determine whether an individual has Attention Deficit Hyperactivity Disorder (ADHD) comprising: providing a group of individuals a segment of which is known to have ADHD and a segment of which is known to be normal and not have ADHD; testing each individual in the group by sampling the peripheral skin temperature of the individual during a pre-determined time interval when the subject is in an inactive state to provide sampled peripheral skin temperature data, and analyzing the sampled peripheral skin data to produce a parameter value for that individual; and processing the individual parameter values for all of the members of the group to determine a threshold parameter value which is acceptable for determining whether or not an individual has ADHD when tested by said testing procedure.

Description

FIELD OF THE INVENTION [0001] This invention relates in general to a technique for diagnosing Attention Deficit Hyperactivity Disorder (ADHD) and more particularly to a technique for measuring an individual's peripheral temperature to determine values indicative of ADHD. BACKGROUND OF THE INVENTION [0002] ADHD is the most common neurobehavioral disorder of childhood as well as among the most prevalent health conditions affecting school-aged children. Between 4% and 12% of school age children (several millions) are affected. $3 billion is spent annually on behalf of students with ADHD. Moreover, in the general population, 9.2% of males and 2.9% of females are found to have behavior consistent with ADHD. Upwards of 10 million adults may be affected. [0003] ADHD is a difficult disorder to diagnose. The core symptoms of ADHD in children include inattention, hyperactivity, and impulsivity. ADHD children may experience significant functional problems, such as school difficulties, academic...
