These studies suggest stroke-like symptoms can be caused by focal infarction or hemorrhage in the brain, spinal cord, or retina, with hypertension being a significant risk factor.

Stroke-like symptoms can arise from various underlying conditions and mechanisms. Understanding these causes is crucial for timely diagnosis and treatment. This article synthesizes research findings on the primary causes of stroke-like symptoms, focusing on ischemic and hemorrhagic strokes, nonmotor symptoms, gender differences, and atypical presentations.
Ischemic stroke, which accounts for the majority of strokes, is primarily caused by blood clots that obstruct blood flow to the brain. These clots can form in the heart or blood vessels and travel to the brain, leading to a blockage that results in brain injury . Abnormal blood flow due to conditions like arteriolosclerosis or cardioembolism also contributes significantly to ischemic strokes.
Hemorrhagic stroke occurs when a blood vessel in the brain ruptures, leading to bleeding within the brain tissue. This type of stroke is often associated with vascular abnormalities such as aneurysms or arteriolosclerosis . The bleeding can cause significant brain damage and is a critical medical emergency.
Stroke survivors often experience nonmotor symptoms that can be as debilitating as physical impairments. These include depression, anxiety, fatigue, and cognitive deficits such as memory loss and aphasia . Emotional lability and personality changes are also common, complicating the recovery process. Treatments for these symptoms include behavioral rehabilitation and, in some cases, noninvasive brain stimulation and pharmacological interventions.
Research indicates that women may experience different stroke symptoms compared to men, which can lead to delays in diagnosis and treatment. Women are more likely to report nontraditional symptoms such as changes in mental status, lightheadedness, and headaches . These differences underscore the need for gender-specific approaches in stroke diagnosis and management.
Some strokes present with atypical symptoms, including neurogenic pain. This pain can manifest as acute trigeminal neuralgia, atypical facial pain, or hemi-sensory pain, often described as burning or sharp. These atypical presentations can complicate the diagnosis, as they may not immediately suggest a stroke.
Several risk factors increase the likelihood of stroke, including hypertension, diabetes, hyperlipidemia, and atrial fibrillation . Clinical features of stroke vary depending on the affected brain region and can include motor and sensory impairments, speech and language disorders, and mental dysfunction .
Stroke-like symptoms can result from a variety of causes, including ischemic and hemorrhagic events, nonmotor impairments, and atypical presentations. Understanding these diverse causes is essential for accurate diagnosis and effective treatment, ultimately improving outcomes for stroke patients.
