Cerebral palsy is usually diagnosed within the first two years of a child’s life, but in milder cases, it might take longer. Usually, doctors carry out a developmental evaluation which involves looking at how a child moves, their muscle strength, reflexes, and posture. A child’s medical history will also be investigated to understand if a specific issue, such as a birth injury, caused the issue. Additional tests like brain scans or genetic testing might also be carried out to assist in diagnosis.
