Bilateral Stroke or Cerebrovascular Accident: This is the most direct explanation for tingling on both sides of the body in the context of a stroke. Strokes can cause a variety of sensory symptoms, including tingling, depending on the area of the brain affected.

Multiple Sclerosis (MS): MS is an autoimmune disease that affects the brain and spinal cord, leading to a wide range of neurological symptoms, including tingling or numbness in various parts of the body. While not typically described as a stroke, MS can mimic stroke-like symptoms.
Migraine with Aura: Some migraines are preceded by an aura, which can include neurological symptoms such as tingling or numbness on one or both sides of the body. Although migraines are not strokes, they can sometimes be confused with them.
Transient Ischemic Attack (TIA): Often referred to as a "mini-stroke," TIAs are temporary periods of symptoms similar to those of a stroke. A TIA doesn't cause permanent damage, but it's a warning sign of a future stroke.

Spinal Cord Infarction: This is a serious condition where the blood supply to the spinal cord is interrupted, leading to damage or destruction of spinal cord tissue. Symptoms can include sudden loss of sensation, including tingling, below the level of the infarction.
Subarachnoid Hemorrhage: Bleeding into the space surrounding the brain can cause sudden, severe symptoms, including tingling or numbness, especially if the bleed affects areas responsible for sensory perception.
Cervical Spine Injury or Disease: Conditions affecting the cervical spine, such as a herniated disk or spinal stenosis, can compress nerves or the spinal cord, leading to tingling or numbness in the arms or legs.

Mitochondrial Encephalomyopathy, Lactic Acidosis, and Stroke-like Episodes (MELAS): A rare mitochondrial disorder that can cause stroke-like episodes, among other symptoms. These episodes can include tingling or numbness.
Susac Syndrome: A rare condition characterized by small vessel vasculopathy that can lead to stroke-like symptoms, including tingling or numbness, due to the involvement of the brain and retina.
Central Nervous System Vasculitis: Inflammation of the blood vessels in the brain and spinal cord can lead to a variety of neurological symptoms, including stroke-like symptoms such as tingling or numbness.
