Yes, panic attacks can resemble seizures. With a panic attack, you can have symptoms that are similar to seizures, such as muscle spasms or shaking, confusion, dizziness, tingling sensation in arms and legs, fainting, and fatigue. These symptoms that resemble seizures in a panic attack are due to the hyperventilation that occurs with a panic attack, where you are breathing fast and your breaths are shallow. The rapid breathing causes too much carbon dioxide being blown off, which leads to a rise in blood pH, known as respiratory alkalosis. This condition leads to the symptoms that resemble seizures.
