Blank stares, déjà vu, sudden confusion: Neurologists explain the subtle symptoms that often go unnoticed and why early diagnosis matters

When people think about epilepsy, dramatic scenes often come to mind. A person collapsing, shaking violently, or losing consciousness. Films and television have reinforced this image for decades.But neurologists say the earliest signs of epilepsy rarely look like that. In many cases, they are quiet, brief, and easy to dismiss. A child staring into space for a few seconds. A teenager feeling an unexplained sense of déjà vu. A colleague suddenly pausing mid-sentence before returning to normal.These moments can pass so quickly that families brush them aside as distraction, stress, or fatigue. Yet neurologists warn that such subtle episodes may be the brain’s early signal of seizure activity. Recognizing them early can prevent complications and help people receive treatment before the condition disrupts school, work, or daily life.Public perception of epilepsy has long been shaped by severe seizures. As a result, milder signs are frequently overlooked. Dr Aniruddha Vasant More, Consultant Neurologist at Jupiter Hospital, Thane, said, “However, most families believe that epilepsy is related to severe seizures that cause people to fall or have convulsions. This has caused the public to misunderstand the condition. In fact, the initial signs of epilepsy can be minor and may include short periods of staring, confusion, unusual sensations, or short periods of time when the individual seems disconnected from the environment. These can be short-lived, taking only a few seconds, and people may think that the individual is daydreaming or distracted.”Globally, epilepsy affects more than 50 million people. India carries a significant share of this burden, with nearly 10 million people in the country live with epilepsy.Despite this, awareness about the early warning signs remains limited.Unlike the seizures commonly shown in movies, many early episodes involve brief interruptions in brain activity. These moments can last only a few seconds.Dr Prashant Makhija, Consultant Neurologist at Wockhardt Hospitals, Mumbai Central, explains that seizures do not always involve dramatic body movements.“When people think about seizures, they usually imagine vigorous jerking of the arms and legs, frothing from the mouth, tongue biting, or loss of bladder control. This type of episode is known as a generalised tonic-clonic seizure and is the form most commonly shown in movies and television. However, not all seizures appear in this dramatic way. In many cases, the signs can be subtle and last only a few seconds.”These episodes may occur without warning. Afterward, the person often returns to normal and may not even remember the event. Early epilepsy symptoms can be even harder to recognise in younger people.Dr More explains that behavioral changes may hide the neurological problem.“Children and young people may be at a higher risk of not being recognized as they may be experiencing behavioral changes that may be misunderstood as attention deficit or mood swings.”A child who suddenly struggles to focus in class or appears distracted may not always be experiencing a learning problem. Sometimes the brain may be briefly interrupting normal activity.Neurologists say repeated déjà vu, sudden fear, or brief jerks in the hand or face can also be early clues. If these events happen often, they can slowly affect school performance, confidence, and social life.One important fact often surprises families: not every seizure means epilepsy.Dr Makhija explains that several temporary conditions can trigger a single seizure, “A single seizure does not always mean a person has epilepsy. A seizure can occur as a one-time event due to temporary causes such as low blood sugar, electrolyte imbalance, high fever, lack of sleep, or excessive alcohol intake. Epilepsy is diagnosed when a person has recurrent seizures or when the brain shows a tendency to develop repeated episodes.”Because early symptoms may be mild, diagnosis can sometimes be delayed. Families may attribute unusual behavior to stress, fatigue, or distraction.But when similar episodes occur repeatedly, medical evaluation becomes essential.Not all seizures happen during the day. Some occur during sleep and may remain hidden for months.Dr Makhija notes that a person may suddenly wake up at night feeling confused, look around briefly, or show unusual movements before falling back asleep.In the morning, the person may feel tired, disoriented, or unable to recall what happened.Because these signs occur in private, they may never be noticed unless someone shares the same room or observes repeated disturbances. Early recognition of epilepsy can significantly improve long-term outcomes.Dr More emphasizes the role families play in identifying unusual patterns.“Awareness within families plays an important role in early diagnosis. If unusual episodes keep repeating, it is important to seek medical evaluation rather than ignoring them. Early identification allows treatment to begin sooner and helps prevent injuries, learning difficulties, or more severe seizure episodes.”Modern treatments, including anti-seizure medications and lifestyle adjustments, help many people manage the condition effectively.With proper treatment, neurologists say most individuals with epilepsy can study, work, drive safely when permitted, and lead stable lives.Recognising those subtle signals can make all the difference.Medical experts consulted This article includes expert inputs shared with TOI Health by: Dr Aniruddha Vasant More, Consultant Neurologist at Jupiter Hospital, Thane.Dr Prashant Makhija, Consultant Neurologist at Wockhardt Hospitals, Mumbai Central.Inputs were used to explain how subtle neurological symptoms such as blank stares, repeated déjà vu, or sudden confusion may sometimes signal underlying seizure disorders, highlighting why these early warning signs are often overlooked and why timely medical evaluation and diagnosis are important.
