Introduction

When blood cannot reach a section of the brain for a long enough period of time to cause harm, a stroke occurs. The neurons in this part of the brain perish if the blood flow isn't providing them with oxygen. Depending on the part of the brain affected, this neuronal death can result in a variety of symptoms, including headache, muscular weakness or paralysis, speech difficulties, sensory issues, memory loss, and disorientation.

02

The explanation for the correct answer

Blood clots frequently cause stroke, however they can also result from a weak blood artery breaking.

03

The explanation for incorrect options

The rest of the options are irrelevant to the question.
