👉 Bradydactylia is a medical condition that affects the development of the brain and spinal cord. It is characterized by an abnormal number or size of ventricles, which are structures in the brain that process the blood in the veins of the brain and spinal cord. This can lead to various symptoms such as difficulty breathing, seizures, and tremors. Bradydactylia is also known as a "brain spasm" because it causes muscle spasms or jerky movements.
