Seizure
Brain tumors could push and press some nerve cells in your cognitive system. This might interfere with some electrical signals and lead to seizures. In many cases, this can be the earliest sign of a growing mass, but you can have a seizure at any stage of the condition. Around 50% of patients with brain tumors have at least a seizure. However, keep in mind that it can also be caused by drug withdrawal, brain diseases, or neurological issues. Make sure to get medical attention immediately as a seizure can be life-threatening and cause many severe complications if left untreated. [3]
