A stroke occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. This is a serious medical emergency requiring immediate attention. Strokes are broadly classified into two main categories: ischemic strokes, caused by a blockage in a blood vessel supplying the brain, and hemorrhagic strokes, caused by bleeding in or around the brain. Strokes present a range of symptoms, some of which can be mimicked by other medical conditions.
Seizures
Seizures are characterized by abnormal electrical activity in the brain. Patients may experience temporary confusion. Like strokes, seizures can cause numbness, tingling, or weakness in the limbs.
Following a severe seizure, some individuals may experience Todd's paralysis, a temporary inability to move part or all of the body. This condition can also affect speech and vision. The paralysis typically lasts for about 30 minutes but can persist for up to 36 hours.
Migraines
Migraines are a chronic neurological condition characterized by severe, often one-sided headaches that can last from 4 to 72 hours. Migraines and strokes share some common symptoms, including headache and dizziness. While a migraine can be intensely painful, it typically does not result in the same long-term consequences or fatality as a stroke. However, some types of migraines can increase the risk of stroke.

Bell's palsy
Bell's palsy is a condition affecting the facial nerve, which controls facial muscles. Patients with Bell's palsy experience sudden weakness or paralysis on one side of the face, sometimes mimicking the facial drooping seen in stroke.
Brain tumors
Brain tumor symptoms vary depending on the tumor's location. Common symptoms include headaches, difficulty with balance, and weakness in the arms or legs. Brain tumors can also cause speech and vision problems, confusion, and memory loss.
Multiple sclerosis
Multiple sclerosis (MS) is an autoimmune disease in which the body's immune system attacks the protective covering of nerve cells in the brain and spinal cord. Individuals with MS may experience vision problems, numbness, tingling, and muscle weakness, similar to stroke symptoms.
Low or high blood sugar
Low blood sugar (hypoglycemia) can mimic stroke symptoms, including unconsciousness, clumsiness, and weakness on one side of the body. Other symptoms include dizziness, tingling around the mouth, and headaches. High blood sugar (hyperglycemia) can also cause blurred vision, weakness, and disorientation.
Sepsis and other infections
Sepsis is the body's overwhelming and life-threatening response to infection, which may originate in the skin, lungs, kidneys, or intestines. If left untreated, sepsis can progress rapidly, leading to multiple organ failure and death. Sepsis can cause confusion, and in severe cases, its symptoms can closely resemble those of a stroke.
Infections of the brain and spinal cord can also cause stroke-like symptoms. Encephalitis, often caused by viruses, can cause confusion and difficulty moving parts of the body, along with vision problems and speech impairment.
