Spastic
92
Spastic CP
Characterized by spasticity in the muscles leading to stiffness, resistance to movement, and contractures (loss of joint movement), the sudden involuntary muscle contractions or spasms result from damage to the frontal lobe of the cerebral cortex.
93
Ataxic CP
Associated with balance, coordination, and depth perception
Caused by damage to the cerebellum
Affected patients have poor coordination, walk with a wide based gait and may have difficulty with quick or precise movements (6%)
94
Mixed CP
A combination of symptoms from different types, often spastic and dyskinetic
95
Dyskinetic CP
Characterized by slow, uncontrolled movements that usually affect the hands, feet, arms, or legs and sometimes the face causing drooling and grimacing.
Movements may increase with emotions stress and disappear during sleep
Children with this may have difficulties with articulation. This is caused by problems with speech muscle coordination
People often think that children with CP have a mental or emotional problems because of their awkward movements
96
This type of CP ONLY involves motor centers, resulting from damage to the basal ganglia (6%)
Dyskinetic CP
97
Etiology of CP
Genetic mutation, maternal infections, hypoxia at birth, infections/injury that affect brain development in infancy
98
Oral findings with CP
