What is a hallmark manifestation of Cerebral Palsy in newborns?

Motor weakness is indeed a hallmark manifestation of cerebral palsy in newborns. This condition affects the areas of the brain that control movement and posture, leading to various degrees of weakness in the muscles. In infants, this may present as difficulty in controlling movements, maintaining posture, or achieving developmental milestones such as rolling over or sitting up.

Cerebral palsy encompasses a range of motor disorders, and the weakness can be more pronounced on one side of the body or can affect the entire body. These motor difficulties are typically attributable to the brain's inability to send appropriate signals to the muscles, resulting in reduced functional ability.

Other manifestations like reflexes might be somewhat affected, but decreased reflexes are more indicative of other neurological conditions rather than cerebral palsy specifically. Similarly, a high-pitched cry and prolonged sleep patterns are not specific indicators of cerebral palsy but could be encountered in various infant health issues. Therefore, recognizing motor weakness is crucial for early identification and intervention for individuals with cerebral palsy.
