Head Injury and IQ: Understanding Potential Cognitive Impacts

It is possible for an IQ to decrease if someone hits their head and their skull starts to go numb. This can happen due to a number of factors, including:

- Brain injury: A head injury can damage the brain, which can lead to a decrease in IQ. The severity of the brain injury will determine the extent of the IQ decrease.

- Hematoma: A hematoma is a collection of blood that can form in the brain after a head injury. This can put pressure on the brain and lead to a decrease in IQ.

- Hydrocephalus: Hydrocephalus is a condition in which there is an excess of cerebrospinal fluid in the brain. This can put pressure on the brain and lead to a decrease in IQ.

- Infection: An infection in the brain can damage the brain and lead to a decrease in IQ.

If you have hit your head and your skull starts to go numb, it is important to seek medical attention immediately. Early diagnosis and treatment can help to minimize the risk of a decrease in IQ.
