What are the signs and symptoms of Down syndrome?

The baby with Down syndrome has a hallmark appearance. However, every aspect of the appearance does not need to be present as the phenotype can be markedly different for each patient.

Commonly, there is a small head and short neck, a flat face, and upward slanting eyes. Ears are flat and positioned lower than normal. The tongue protrudes and seems to be too large for the mouth. Hands tend to be wide, with short fingers and there is just a single flexion crease in the palm. Joints tend to be more flexible and muscles may lack tone.

The patient may have growth retardation and though as a baby may be normal size, will not grow as tall. Average height for an adult male with Down syndrome is 5 ft 1 in and for a female it is 4 ft 9 in. Bowleggedness is common. Obesity occurs with aging.

There is decreased mental function and the IQ may range from mild disability (50 to 70) to moderate (35 to 50). For patients with Mosaic Down Syndrome, the IQ can be 10 to 30 points higher. There can be language development delay both from hearing impairment and speech delay. Gross motor skills like crawling and walking can be slow to mature and fine motor skills may take time to develop.

My child is four years old. He just starting jumping this year. He speaks around ten words verbally but he signs more than ten. He can run, walk up and down stairs without help, eat most foods without assistance. He smiles a lot and to me he is strong and smart. I hope this helps someone. He is a wonderful gift from God!

My son 2.5 years is diagnosed as Down Syndrome. He has mild hole in the heart. His weight and height is normal and is also sharp minded but he doesn't speak yet. He stands up himself and tries to walk for two or three steps. His treatment is being carried out through the Children Hospital.
