Stroke symptoms resurface: Understanding, remedial measures
Ischemic stroke recrudescence, also known as anamnestic syndrome, is a concerning condition where previous stroke-related neurological deficits reappear or worsen. This phenomenon is not well-characterized and is believed to be fairly rare or uncommon.
Common causes and triggers for ischemic stroke recrudescence typically involve transient factors that exacerbate brain ischemia or worsen the underlying vascular pathology. These factors include systemic hypoperfusion, infections/inflammation, cardiovascular arrhythmias, embolism, and vascular risk factors like hypertension and diabetes.
Systemic factors that reduce cerebral perfusion, such as hypotension, dehydration, anemia, fever, and metabolic disturbances (e.g., hypoglycemia or hyperglycemia), can transiently worsen ischemic areas and cause recrudescence. Infections and systemic inflammation can provoke systemic inflammatory responses that increase vascular inflammation or coagulability, potentially triggering recurrent ischemic activity.
Cardiovascular conditions, such as atrial fibrillation and other arrhythmias, may increase embolic risk, while worsening of large-artery atherosclerosis can reduce cerebral blood flow, both precipitating recrudescence. Recurrent embolism sources, such as paradoxical embolism (e.g., via patent foramen ovale) or cardioembolic sources, can trigger new ischemic events or worsen old ones.
In some conditions, such as chronic rheumatic heart disease, subclinical inflammation and episodic tissue inflammation have been associated with recrudescence through progressive myocardial and valvular fibrosis. Other common stroke risk factors, like hypertension, diabetes, hyperlipidemia, and smoking, contribute to both initial ischemic stroke and its recrudescence by damaging cerebral vasculature.
While direct detailed data on ischemic stroke recrudescence causes is limited, these factors are well-established triggers for recurrence or worsening of cerebral ischemia, leading to recrudescence episodes. It's important to note that recrudescence often involves transient worsening rather than a new infarct, caused by reversible factors impacting brain perfusion or inflammation.
In addition to the above factors, vascular diseases, especially peripheral vascular disease, are risk factors for ischemic stroke recrudescence. Other recognised triggers include insomnia or lack of proper sleep, stress, high cholesterol or high triglyceride levels, and the use of sedating medications, such as benzodiazepines, and anesthetic drugs, such as midazolam hydrochloride and fentanyl citrate.
Ischemic stroke recrudescence tends to reverse on its own, with most people recovering or returning to their poststroke recovery levels roughly a day or two after the symptoms redevelop. However, it's crucial to seek emergency medical assistance if one experiences signs or symptoms associated with a stroke, regardless of whether they have previously experienced a stroke or not.
In summary, understanding the common causes and triggers for ischemic stroke recrudescence is essential for managing and preventing this condition. By recognising and addressing these factors, individuals at risk can take proactive steps to minimise their chances of experiencing recrudescence episodes.
