Do you know what’s really happening when someone says they have a migraine or why a sudden loss of balance might be more than just clumsiness? Neurological disorders are more common than we think. And sometimes far more serious when left untreated. They affect how we move, think, feel, and even breathe. In this blog, a top neurologist in Sarjapur road, Bengaluru, discusses ten common conditions that affect the brain, nerves, and spinal cord. This blog will give you a quick picture of what these disorders look like, what causes them, and how they’re treated.
What Are Neurological Disorders?
Neurological disorders are conditions that affect the brain, spinal cord, or nerves — the parts of your body that control how you think, move, feel, and even breathe. When something goes wrong in this system, it can lead to problems like headaches, memory loss, numbness, or difficulty with movement and coordination. Some common examples include stroke, epilepsy, Alzheimer’s disease, and Parkinson’s disease.
10 Neurological Disorders and Their Symptoms
Let’s check out each of the ten most common neurological disorders in detail.
1. Migraine
Unlike what many people think, a migraine isn’t just a severe headache. It’s a complex neurological condition that affects how you function, think, and feel. It starts with specific triggers like stress, hormonal shifts, lack of sleep, or even certain foods. The cause of migraine isn’t fully understood, but there is also a genetic component to it. Migraine treatment involves avoiding migraine triggers, using medication, and adopting lifestyle changes that reduce flare-ups.
Some of the migraine symptoms include:
-
Throbbing or pulsating pain, which is usually on one side of the head
-
Nausea and sometimes vomiting
-
Sensitivity to light and sound, or even smell

2. Stroke
A stroke occurs when blood flow to a part of the brain is interrupted and there is a cut off in oxygen and nutrients supply to the brain - it results in stroke. A stroke can happen suddenly and without warning, and it is often life-changing. There are two main types of stroke: The first is the ischaemic stroke, which is caused by a clot. The second is the hemorrhagic stroke, which is caused by bleeding in the brain. Both need urgent medical attention. Immediate response to stroke is critical to avoid long-term effects. Stroke treatment depends on the type but often involves clot-busting drugs or surgery, followed by rehabilitation.
Some of the common stroke symptoms include:
-
Numbness or weakness which affects one side of the body
-
Trouble speaking or understanding speech
-
Blurred vision or sudden loss of balance
3. Alzheimer’s Disease
Alzheimer’s disease is a neurodegenerative condition and is the most common reason people develop dementia. The condition is progressive and gradually affects memory, thinking, and daily activities. In the early stages, people experience forgetfulness or confusion and odd thinking. Over time, their reasoning, language, and even the ability to recognize loved ones are affected. The exact dementia causes are yet to be determined, but there’s a mix of genetics, lifestyle, and environmental factors involved. There is currently no cure, but Alzheimer’s treatment can help manage the condition and slow down how fast it progresses.
Some early Alzheimer’s symptoms include:
-
Forgetting recent conversations or events
-
Struggling with familiar tasks or decisions
-
Mood changes or withdrawal from social activities
4. Parkinson’s Disease
Parkinson’s disease is a neurological condition that affects movement and coordination. It also starts gradually. Sometimes the first symptom is a mild tremor in one hand, which gets worse over time. One of the main causes of the disease is dopamine loss in the brain. The prolonged low dopamine affects how nerves communicate. Over time, people with Parkinson’s may find it difficult to walk, stay balanced, or control fine movements with their hands and legs. There’s no cure yet for Parkinson’s. But there are treatments to effectively manage symptoms and improve movement. In some cases, surgical options like deep brain stimulation may be considered.
Some of the common Parkinson’s symptoms include:
-
Shaking or tremors, especially in hands or fingers
-
Stiffness in arms, legs, or neck
-
Slowed movement and poor balance
5. Epilepsy
Epilepsy is a neurological condition where people experience repeated seizures. These seizures happen because of sudden, uncontrolled bursts of electrical activity in the brain. They can look very different from person to person. In some, it may have brief staring spells, while others may lose consciousness or have full-body convulsions. There are many seizure types, and the cause of epilepsy can range from genetic factors to past brain injuries. Epilepsy treatment often involves long-term medication, but some people benefit from dietary changes or surgery in severe cases.
Some common epilepsy symptoms include:
-
Sudden, repetitive movements or twitching
-
Staring blankly or losing awareness for a few seconds
-
Temporary confusion or fainting without a clear reason
6. Multiple Sclerosis (MS)
Multiple sclerosis is an autoimmune condition where the brain and spinal cord are attacked by the body’s own immune system. The condition specifically damages the myelin sheath of the nerve cells. It is the protective layer around nerve fibres which is crucial for the cells. The damage affects how signals travel between the brain and the rest of the body. The symptoms can come and go or get worse over time, depending on the type of MS. While there’s no cure yet, MS treatment can help reduce flare-ups and slow progression.
Some common MS symptoms include:
-
Fatigue and muscle weakness
-
Numbness or tingling in the limbs
-
Difficulty with balance, vision, or coordination
7. Traumatic Brain Injury (TBI)
A traumatic brain injury happens when a sudden impact or a blow to the head occurs. It could be from a fall, a car crash, or a sports injury. The injury disrupts normal brain function and can have lasting effects. Some injuries are mild, like a concussion, while others can cause long-term damage. The effects depend on the part of the brain affected and the severity of the trauma. Early medical intervention is important to dampen the effects. Brain injury rehabilitation often plays a big role in recovery and involves therapies to restore function and independence.
Some of the common TBI symptoms include:
-
Headaches, dizziness, or blurred vision
-
Difficulty concentrating or remembering things
-
Mood changes, irritability, or sleep disturbances
8. Amyotrophic Lateral Sclerosis (ALS)
ALS, also known as Lou Gehrig’s disease, is a progressive neurodegenerative disease that affects the nerve cells responsible for controlling muscle movement. Over time, the nerves lose their ability to send signals, which leads to muscle weakness, stiffness, and eventually paralysis. It usually starts with subtle changes like a weak grip or slurred speech, and then spreads. There's no cure, but ALS treatment focuses on slowing progression and improving comfort through supportive care.
Some early ALS symptoms include:
-
Muscle weakness in the arms, legs, or speech muscles
-
Difficulty swallowing or breathing
-
Increased muscle stiffness or twitching
9. Meningitis
Meningitis is an infection that causes inflammation of the meninges. These are protective layers covering the brain and spinal cord. It can be caused by bacteria, viruses, or in rare cases, fungi. Causes of meningitis can also include tuberculosis or certain medications. Bacterial meningitis is the most serious and needs urgent treatment. Viral meningitis is usually less severe but still needs care. Meningitis treatment depends on the cause and may involve antibiotics, antiviral drugs, and supportive care.
Some of the common meningitis symptoms include:
-
High fever and a stiff neck
-
Severe headache that doesn’t go away
-
Sensitivity to light and confusion
10. Peripheral Neuropathy
Peripheral neuropathy happens when the nerves, which are located outside of the brain and spinal cord get damaged. This nerve damage can be caused by diabetes, infections, injuries, or even certain medications. It usually affects the hands and feet first and can interfere with movement, balance, and daily functioning. The goal of neuropathy treatment is to manage the underlying cause and ease symptoms. Early care makes a big difference.
Some common peripheral neuropathy symptoms include:
-
Tingling, numbness, or burning in the hands or feet
-
Weakness or loss of coordination
-
Sharp, stabbing pain that may come and go
Conclusion
Recognizing the early signs of neurological disorders can make a major difference in outcomes. Symptoms like persistent headaches, muscle weakness, memory issues, or balance problems should never be ignored. Timely diagnosis and the right treatment plan can slow down progression, improve quality of life, and, in many cases, prevent long-term damage.

FAQ's
Early signs often include persistent headaches, unexplained numbness, memory loss, muscle weakness, or difficulty speaking. These symptoms might seem harmless at first, but they could point to underlying conditions like migraine, stroke, or Parkinson’s disease. If they don’t improve or worsen, it’s best to seek medical advice.

It depends on the condition. Some neurological issues like certain infections or migraines can be managed or even resolved with treatment. Others, like Alzheimer’s or Parkinson’s, can’t be cured but can be controlled with medication, therapy, and lifestyle changes to slow progression and improve quality of life.
Not always. While genetics play a role in conditions like Alzheimer’s or epilepsy, many neurological disorders are triggered by lifestyle, infections, injuries, or environmental exposures. For example, stroke is often linked to high blood pressure or diabetes rather than family history alone.
Neurologists use a mix of clinical evaluation, medical history, and diagnostic tests like MRI scans, CT scans, EEGs, or blood tests. These help assess the structure and function of the brain, nerves, and spinal cord to identify the exact issue and plan the treatment.
