Question

Quizplus · Accepted Answer

Janine's symptoms are consistent with those of a concussion, which is a type of traumatic brain injury caused by a blow to the head. Mental confusion, dizziness, and memory problems are common symptoms of a concussion. Unresponsive wakefulness syndrome and brain death are both severe conditions that are unlikely to be the cause of Janine's symptoms. Insomnia, which is a disorder characterized by difficulty falling asleep or staying asleep, does not typically cause mental confusion, dizziness, or memory problems.
