People with Down’s Syndrome usually have slower mental and physical development. Not all people containing the defect are the same. It can range from mild to severe. Difficulty speaking, slow motor development, difficulty with social and practical skills, and delayed language development are some common intellectual symptoms.
Physical symptoms consist of a flat face with an upward slant to the eyes, short neck, deep crease in the palm of the hand, white spots on the iris of the eye, poor muscle tone, loose ligaments, and small hands and feet.
Known health conditions in some people with the disorder are: heart disease (from birth), hearing problems, intestinal problems, eye problems, problems with bone structure and joints, and some present a condition called Dementia, somewhat similar to Alzheimer’s disease causing more personality disorders and decreased reasoning (Shriver 2007).
