Hi, Thanks for writing in. There is electrical activity going on in the brain at all times. This is mapped by doing electroencephalogram which records the waves on the surface of the brain. When there is abnormal brain waves from a hyperactive area then it causes seizures and this is called epilepsy. Epilepsy is another name for seizure disorder. You have got seizures and the EEG is abnormal, therefore a detailed investigation using MRI scan brain is required. The abnormal EEG area should be studied in detail. The answers to your questions are the following. 1. Sinusitis and seizures is not directly related. However an infection from sinuses can rarely reach the brain and cause seizures. This is very rare. 2. Menstrual cycles can be affected by medicines, illnesses and stress. The details of tablet are important to discuss this point 3. It depends on which medicine is there in the tablet. Most medicines are taken after food but some might require to be taken before food. 4. Sun stroke is an environmentally influenced condition and there should be sufficient history of going out in the hot sun. Sun stroke is a metabolic disorder and can lead to seizure or epilepsy. 5. Epilepsy can be from many causes and if your EEG us abnormal then a cause in the brain must be looked for. 6. Epilepsy and seizures are almost the same. Seizure is a single episode and epilepsy is usually for multiple episodes. A fall during first seizure is less likely to cause abnormal EEG and the seizure caused it.
