The human brain operates through electrical signals, categorized into different frequency bands that correspond to various cognitive and physiological states. Among these, delta (0.5–4 Hz) and theta (4–8 Hz) waves play critical roles in brain function, particularly in the frontal lobes, which are responsible for executive functions, decision-making, and emotional regulation. Abnormal activity in these frequencies is linked to various neurological and psychiatric conditions, including schizophrenia, depression, traumatic brain injury (TBI), ADHD, and neurodegenerative diseases. Electroencephalography (EEG) is a key diagnostic tool in assessing delta and theta activity, providing valuable insights into brain function and potential disorders. The Discovery of...

In many developing countries, healthcare systems face significant challenges: limited access to medical facilities, a shortage of healthcare professionals, and inadequate infrastructure. With growing populations and increasing rates of chronic diseases, the demand for quality healthcare continues to rise. Telemonitoring and portable diagnostic devices are now emerging as powerful tools to bridge healthcare gaps, transforming patient care in resource-limited settings and strengthening healthcare structures. The Challenge: Access and Infrastructure Gaps Developing countries often have limited healthcare access, especially in rural and remote areas where a lack of transportation, inadequate medical facilities, and a shortage of trained personnel can make receiving...

Electroencephalography (EEG) and electromyography (EMG) are indispensable tools in neurological and muscular diagnostics. They provide critical insights into the brain’s electrical activity and muscle function, helping doctors diagnose a wide range of conditions, from epilepsy to neuromuscular disorders. However, one of the most persistent challenges in EEG and EMG data acquisition is the impact of noise—unwanted signals that can interfere with the accurate measurement of the patient’s physiological data.   The Impact of Noise in EEG and EMG Data Acquisition When performing EEG or EMG tests, the goal is to measure specific electrical signals—whether it’s the brain’s neural oscillations or the...

Febrile seizures are a common and often alarming occurrence in young children, typically associated with fever but not necessarily indicating a severe health problem. Despite their often-benign nature, febrile seizures require careful evaluation and management to ensure the child's health and provide peace of mind to concerned parents. In this article, we will explore what febrile seizures are, their causes, diagnosis, the role of EEG in their evaluation, treatment options, and how Clarity Medical's portable EEG devices are transforming the diagnostic landscape.   What is a Febrile Seizure? A febrile seizure is a convulsion triggered by fever in infants and...

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition that affects individuals' social interactions, communication skills, and behaviour. As awareness about autism grows, so does the need for understanding, support, and acceptance for individuals on the autism spectrum. World Autism Awareness Day, observed annually on April 2nd, serves as a platform to promote autism awareness, acceptance, and inclusion. In this article, we will delve into the fundamentals of autism, including its definition, challenges faced by autistic individuals, diagnosis methods (including the role of EEG), government and NGO initiatives for support, and the importance of World Autism Awareness Day.   What...

What is Epilepsy? Epilepsy is a chronic neurological disorder characterized by a predisposition to recurrent seizures. Seizures occur due to sudden and abnormal electrical activity in the brain, leading to temporary disruptions in normal brain function. Epilepsy can have various causes, including genetic factors, brain injuries, infections, and developmental disorders. While epilepsy is a chronic condition, seizures can often be managed with appropriate treatment and support.   Symptoms of Epilepsy: The symptoms of epilepsy can vary widely depending on the type of seizure and the areas of the brain affected. Common symptoms may include: > Seizures: Seizures are the hallmark...
