Attention deficit hyperactivity disorder
Attention deficit hyperactivity disorder A behavior disorder originating in childhood in which the essential features are signs of developmentally inappropriate inattention, impulsivity, and hyperactivity. Although most individuals have symptoms of both inattention and hyperactivity-impulsivity, one or the other pattern may be predominant. The disorder is more frequent in males than females. Onset is in childhood. Symptoms often attenuate during late adolescence although a minority experience the full complement of symptoms into mid-adulthood.

Attenuated familial adenomatous polyposis An inherited predisposition to colorectal cancer characterized by fewer than 100 adenomatous polyps in the colon and rectum. It is said to be attenuated because there are fewer polyps than in classic familial adenomatous polyposis (FAP). People with attenuated familial adenomatous polyposis (AFAP) also tend to be older at the diagnosis of their polyps (average age of 44 years) and cancer (average age of 56 years), 10 to 15 years later than in classic FAP. The right side of the colon tends to be involved in AFAP and rectal involvement is rare. AFAP is transmitted in an autosomal dominant manner.
Attenuated FAP Attenuated familial adenomatous polyposis.
