Can a Stroke Cause Excessive Sleepiness and Lack of Energy?

Cerebral infarction, medically known as cerebral ischemia, may lead to lethargy and lack of energy. The clinical symptoms of cerebral infarction include abnormal limb motor function, abnormal limb sensory function, and abnormal neurological function. Details are as follows:

1. Abnormal Limb Motor Function: When cerebral infarction affects the nervous system and more obvious or severe clinical symptoms appear, diagnosis becomes relatively easy. Patients with cerebral infarction may experience unilateral motor dysfunction such as hemiplegia, hemianopia, and unilateral sensory disturbances due to neurological damage.

2. Abnormal Limb Sensory Function: If cerebral infarction affects vital blood vessels, patients may experience abnormal sensory function in one limb, such as numbness and pain.

3. Abnormal Neurological Function: If cerebral infarction affects the dominant hemisphere of the patient, speech dysfunction may occur, causing abnormalities in pronunciation or communication. If cerebral infarction affects basic centers such as the cerebellum or brainstem, symptoms such as dizziness, nausea, vomiting, and even balance disorders or supply dysfunction, dysphagia, nystagmus, or diplopia may also appear.
