Dylan's Condition

Spastic (pyramidal) cerebral palsy
A person with spastic cerebral palsy develops tight muscles in some parts of the body that are unable to relax. Affected joints become stiff and difficult to move. Usually, a person has problems controlling movements, poor coordination and balance, and difficulty talking and eating.

There are four types of spastic CP, grouped according to how many limbs are affected.

Quadriplegia: Both arms and both legs are affected. Usually the trunk and muscles that control the mouth, tongue, and windpipe are affected as well. This makes eating and talking difficult. Babies with spastic quadriplegia may:
Have problems sucking and swallowing.
Have a weak or shrill cry.
Have a very relaxed and floppy body or a very stiff body. When held, they may arch their backs and extend their arms and legs.
Be irritable and jittery when awake. For example, they may startle easily.
Sleep a lot or show little interest in what is going on around them.

Total body cerebral palsy affects the entire body to some degree. Complications of cerebral palsy and other medical problems are more likely to develop when the entire body is involved rather than isolated parts. Total body cerebral palsy may include any of the following:

Spastic quadriplegic cerebral palsy (This is the type of CP that Dylan has)
Dyskinetic cerebral palsy
Ataxic cerebral palsy

Symptoms   
Seizures
Muscle contractions
Difficulty sucking or feeding
Delayed development of motor skills, such as reaching, sitting, rolling, crawling, walking, and so on
Motormental retardation in children is generally related to significant central nervous system damage or abnormality. The term refers specifically to delayed development of cognitive skills (like speech) and delayed development of motor skills (such as walking).There can be different degrees of mental retardation. They include not meeting certain normal developmental milestones.Common Causes Cerebral hemorrhage (bleeding in the brain)
Speech problems (dysarthria)
Visual problems
Spasticity
Joint contractures that slowly get worse
Limited range of motion
