Many people brush off unusual body signals, chalking them up to everyday factors like stress, fatigue, or getting older. Neurologists, however, stress that certain signs deserve prompt attention because they might point to serious underlying conditions. In discussions with Time magazine, experts outlined eight key symptoms that warrant immediate medical evaluation. Ignoring them could delay critical diagnosis and treatment.
One concerning issue is sudden double vision, particularly when it affects just one eye. Dr. Luis Cruz-Saavedra, a neurologist at Memorial Hermann health system, advises taking this seriously and seeking care right away. Possible causes range from multiple sclerosis and stroke to aneurysm, myasthenia gravis, brain tumor, or infection. Quick action helps identify the root problem early.
Another red flag involves weakness in a single arm or leg without an obvious reason. People might notice dragging a foot, limping, or struggling to lift items with their usual hand. This asymmetry often signals something amiss in the nervous system. Consulting a doctor promptly can rule out or address potential threats.
Brief episodes of zoning out also raise alarms. These moments last seconds, where someone appears absent and later recalls nothing about it. Dr. Cruz-Saavedra links them to seizures starting in the temporal lobe, a brain area tied to memory and emotions. Others often spot these before the person does.
Sudden speech difficulties represent a classic emergency sign. Slurred words, slow talking, or trouble finding terms can appear out of nowhere. Dr. Enrique Leira, who leads the cerebral vascular disease department at the University of Iowa, urges immediate help in such cases. “This may be a sign of a stroke, which often occurs suddenly,” he notes.
Intense headaches that strike abruptly during physical activity demand attention too. Most headaches prove benign, but certain patterns stand out. Dr. Leira explains that a severe one arriving without buildup, especially under exertion, needs urgent review. It differs from typical tension or migraine pain.
Numbness in the feet or fingers goes beyond simple tingling. True loss of sensation suggests nerves failing to work properly. Dr. Andrew Dorsch from Rush University system recommends checks to pinpoint causes, which might include diabetes or immune attacks on nerves. Distinguishing numbness from fleeting pins-and-needles matters greatly.
Struggling to rise from a seated position can hint at more than joint stiffness. Age brings some rigidity, yet persistent difficulty merits investigation. Dr. Dorsch suggests exams to assess muscles, nerves, spinal cord, or family-linked conditions like Parkinson’s disease or amyotrophic lateral sclerosis (ALS). Sharing family history aids the process.
Frequent déjà vu experiences complete the list of concerns. Occasional feelings of “already seen” feel normal for many. When they happen weekly or more, though, they may tie to temporal lobe seizures again. Dr. Dorsch advises evaluation for unusually repeated episodes.
These warnings underscore how the nervous system communicates distress through subtle or stark changes. Conditions like stroke involve blocked or burst brain blood vessels, leading to rapid cell damage if untreated. Multiple sclerosis features immune attacks on nerve coverings, causing varied symptoms over time. Parkinson’s and ALS progressively affect movement and strength, often with genetic components.
Myasthenia gravis weakens muscles due to communication breakdowns between nerves and muscles. Aneurysms pose risks as weakened vessel walls that could rupture. Brain tumors, whether benign or malignant, pressure surrounding tissues. Early detection across these issues improves outcomes significantly.
