Neurological Disorders: Symptoms, Causes and Types

Neurological disorders are a wide range of health conditions that can affect the brain, spinal cord, and nerves. These neuro disorders can impact various aspects of daily life, from movement and sensation to cognition and behaviour. It is crucial to know about the symptoms, causes, and types of neurological disorders for early diagnosis and effective treatment. In this article, we’ll explore these aspects in detail to provide a clearer picture of neurological health.

What Are Neurological Disorders?

Neurological disorders are conditions that impact the nervous system, which includes the central nervous system, which contains the brain and spinal cord and the peripheral nervous system, consisting of nerves that branch out from the spinal cord). Various factors, like genetic predisposition, environmental influences, infections, and injuries, are responsible for these disorders.

Prevalence of Neurological Disorders

According to the World Health Organization (WHO), around 1 in 6 people worldwide are likely to experience a neurological disorder at some point in their lives. In Australia, neurological conditions are among the leading causes of disability and death. Common examples include stroke, epilepsy, multiple sclerosis, Parkinson’s disease, and Alzheimer’s disease.

Common Symptoms of Neurological Disorders

The symptoms can vary depending on the specific condition and the affected areas of the nervous system. Some common symptoms include:

• Headaches: Frequent or severe headaches can indicate underlying neurological issues.

• Seizures: These are caused by sudden uncontrolled electrical disturbances in the brain.

• Numbness or Tingling: Abnormal sensations in the limbs can be a signal of nerve damage or compression.

• Weakness: Muscle weakness can result from various neurological conditions affecting motor pathways.

• Cognitive Changes: Memory loss, confusion, or difficulty concentrating may indicate cognitive decline or dementia.

• Movement Disorders: Tremors, rigidity, or difficulty with coordination can be signs of conditions like Parkinson’s disease.

If you have these symptoms for a long time, consult a healthcare professional.

Types of Neurological Disorders

Neurological disorders can be classified into several categories based on their causes and effects. Here are some common types:

Neurodegenerative Disorders

The conditions lead to the gradual degeneration of nerve cells in the areas of brain and spinal cord.

• Alzheimer’s Disease: A type of dementia that impacts memory, thinking, and behavior. It is characterized by the buildup of amyloid plaques in the brain.

• Parkinson’s Disease: A movement disorder caused by the loss of dopamine-producing neurons in the brain. Symptoms include tremors, stiffness, and balance problems.

• Amyotrophic Lateral Sclerosis (ALS): Also called Lou Gehrig’s disease, this disease affects motor neurons, leading to muscle weakness and atrophy.

Vascular Disorders

These disorders are related to blood flow issues in the brain.

• Stroke: This occurs when blood supply to brain part is interrupted or reduced. Symptoms includes sudden numbness or weakness on one side of the body and difficulty speaking.

• Transient Ischaemic Attack (TIA): Often called a “mini-stroke,” TIAs are temporary disruptions in blood flow that can be a warning signs for future strokes.

Inflammatory Disorders

These conditions involve inflammation of the nervous system.

• Multiple Sclerosis (MS): It is an autoimmune disorder where our own immune system attacks the protective covering of nerves (myelin), leading to communication issues between the brain and body.

• Guillain-Barré Syndrome: A rare condition where the immune system attacks peripheral nerves, causing weakness and sometimes paralysis.

Infectious Disorders

Infections can also affect the nervous system.

• Meningitis: This condition involves an infection of the protective membranes surrounding the brain and spinal cord. Symptoms often include fever, headache, and a stiff neck.

• Encephalitis: Inflammation of the brain is often caused by viral infections.

Developmental Disorders

These are conditions that affect how a person develops physically or mentally.

• Autism Spectrum Disorder (ASD): A developmental disorder that impacts communication skills and behavior.

• Attention Deficit Hyperactivity Disorder (ADHD): A condition characterised by difficulty maintaining attention and hyperactive behaviour.

Causes of Neurological Disorders

The causes of neurological disorders are diverse and can include:

• Genetic Factors: Some neurological conditions have a hereditary component.

• Environmental Factors: Exposure to toxins or infections during pregnancy or early childhood can increase risk.

• Lifestyle Factors: Poor diet, lack of exercise, smoking, and excessive alcohol consumption can contribute to neurological health issues.

• Head Injuries: Trauma to the head can lead to long-term neurological problems.

Seeking Help from a Specialist

If you suspect you have a neurological disorder or are experiencing concerning symptoms, consulting a qualified neurologist is crucial. A specialist will conduct thorough assessments—such as imaging tests (MRI or CT scans), blood tests, or neuropsychological evaluations—to determine an accurate diagnosis.
