Movement Disorders: Types, Symptoms & When to Seek Help

What are Movement Disorders?

Movement disorders are a group of neurological conditions that affect your body's ability to produce and control normal movement patterns. These conditions originate in the nervous system, specifically disrupting the brain regions responsible for coordinating muscle activity and movement control.

Movement disorders can manifest as either reduced movement (hypokinetic conditions like Parkinson's disease) or excessive, uncontrolled movement (hyperkinetic conditions such as essential tremor, chorea, or other involuntary movements). More than 30 different diseases are classified as movement disorders, with symptoms varying widely among individuals but often progressing over time.

How the Nervous System Controls Movement

Your nervous system orchestrates all voluntary and involuntary movements through an intricate network of neural pathways connecting your brain, spinal cord, and muscles. The brain sends precise signals through the spinal cord to peripheral nerves, instructing muscles when to contract and relax in coordinated patterns.

Movement disorders occur when disruptions affect these neural communication pathways. The sensorimotor cortex, basal ganglia, and cerebellum play crucial roles in movement coordination. When damage or dysfunction occurs in these brain regions, it leads to the characteristic abnormal movement patterns seen in various movement disorders. This disruption can stem from genetic factors, neurodegeneration, or environmental influences affecting how your brain processes and executes movement commands.

Types of Movement Disorders

Understanding different movement disorder types helps recognise symptoms and seek appropriate treatment:

• Parkinson's disease: A progressive neurological condition causing tremors, muscle rigidity, slowness of movement, and balance problems.
• Essential tremor: Involuntary rhythmic shaking, primarily affecting hands and neck during voluntary movement.
• Dystonia: Sustained muscle contractions causing repetitive, twisting movements and abnormal postures.
• Huntington's disease: Inherited disorder characterised by chorea (irregular, dance-like movements) and cognitive decline.
• Tourette syndrome: A neurological condition involving repetitive movements and vocal sounds called tics.
• Ataxia: A degenerative disorder affecting coordination, balance, and speech.
• Myoclonus: Sudden, brief muscle jerks or twitches.
• Restless legs syndrome: Uncomfortable leg sensations creating an urge to move.
• Multiple system atrophy: A rare condition affecting movement, blood pressure, and bladder control.
• Progressive supranuclear palsy: A rare neurodegenerative disorder affecting walking, balance, and eye movement control.

Common Symptoms of Movement Disorders

Movement disorders' symptoms vary depending on the specific condition, but several key indicators warrant attention:

• Tremors or involuntary shaking movements, especially at rest or during activity.
• Muscle rigidity or stiffness that affects normal movement.
• Bradykinesia (abnormally slow movement).
• Difficulty walking or noticeable changes in gait patterns.
• Loss of balance and coordination problems.
• Involuntary muscle contractions or spasms.
• Jerky, irregular movements affecting arms, legs, or the entire body.
• Speech difficulties or voice changes.
• Excessive fidgeting or inability to remain still.
• Facial grimacing or unusual expressions.
• Problems with fine motor skills, like writing or buttoning clothes.

What Causes Movement Disorders?

Movement disorders' causes are diverse and often complex, involving multiple factors:

• Genetic mutations: Inherited conditions like Huntington's disease result from specific gene defects.
• Neurodegeneration: Progressive damage to brain cells, particularly in areas controlling movement.
• Neurotransmitter imbalances: Disruption in chemical communication between brain cells.
• Environmental toxins: Exposure to certain chemicals or heavy metals.
• Brain injuries: Trauma affecting movement-controlling brain regions.
• Infections: Viral or bacterial infections affecting the nervous system.
• Medication side effects: Certain drugs can trigger movement abnormalities.
• Autoimmune conditions: Immune system attacks on components of the nervous system.

Risk Factors You Should Know

Understanding movement disorders causes helps healthcare providers develop targeted treatment approaches and may inform prevention strategies for at-risk individuals.

Several factors can increase your likelihood of developing movement disorders:

• Age: Many movement disorders become more common with advancing age, particularly after 60.
• Family history: A genetic predisposition significantly increases the risk of inherited conditions.
• Gender: Some conditions show gender preferences; for example, men develop Parkinson's disease more frequently.
• Environmental exposure: Occupational or residential exposure to pesticides, heavy metals, or industrial solvents.
• Previous head injuries: Traumatic brain injuries may increase susceptibility to certain movement disorders.
• Medication history: Long-term use of certain psychiatric or antiemetic medications.

Possible Complications

Without proper management, movement disorders can lead to serious complications:

• Progressive decline in mobility and independence
• Increased fall risk and potential injuries
• Speech and swallowing difficulties (dysarthria and dysphagia)
• Cognitive impairment and dementia
• Depression and anxiety disorders
• Social withdrawal and isolation
• Sleep disturbances, including insomnia or excessive daytime sleepiness
• Nutritional problems due to eating difficulties
• Respiratory complications from swallowing issues
• Reduced quality of life for patients and families

How Movement Disorders Are Diagnosed

Healthcare providers use a systematic approach to diagnose movement disorders:

1. Comprehensive medical history: A detailed discussion of symptoms, family history, medications, and potential environmental exposures.
2. Neurological examination: Assessment of reflexes, muscle strength, coordination, gait, and movement patterns.
3. Symptom observation: Careful evaluation of abnormal movements during rest and activity.
4. Cognitive assessment: Testing memory, thinking skills, and mental function.
5. Differential diagnosis: Ruling out other conditions that might mimic movement disorders.

Tests for Movement Disorders

Diagnostic testing helps confirm movement disorders and guide treatment decisions:

• Brain imaging: MRI or CT scans to identify structural abnormalities.
• Blood tests: Comprehensive metabolic panel to assess overall health.
• Autoimmune Parkinsonian Profile: Specialised testing for immune-related movement disorders.

FAQs

What are the early signs of a movement disorder?

Early movement disorder symptoms often include subtle tremors, slight stiffness, balance problems, or changes in handwriting. You might notice difficulty with fine motor tasks, occasional muscle spasms, or mild coordination problems. These symptoms typically develop gradually and may initially be dismissed as normal ageing or stress-related issues.

Can movement disorders be cured?

Currently, most movement disorders cannot be completely cured, but many can be effectively managed with appropriate treatment. Movement disorder treatment focuses on controlling symptoms, slowing progression, and maintaining quality of life through medications, therapies, and lifestyle modifications. Early intervention often leads to better long-term outcomes.

What is the most common movement disorder?

Essential tremor is the most common movement disorder, affecting approximately 1% of the population worldwide. Parkinson's disease is the second most common, with over 8.5 million people affected globally according to WHO estimates. Both conditions significantly impact daily functioning but respond well to appropriate treatment approaches.

Are movement disorders hereditary?

Some movement disorders have genetic components, particularly Huntington's disease, certain types of dystonia, and some forms of Parkinson's disease. However, many movement disorders result from complex interactions between genetic predisposition and environmental factors. Genetic counselling can help assess your risk if you have a family history of these neurological conditions.

Is Parkinson's a movement disorder?

Yes, Parkinson's disease is one of the most well-known movement disorder types. It affects the brain's ability to produce dopamine, leading to characteristic symptoms, including tremors, rigidity, bradykinesia, and balance problems. The WHO reports that Parkinson's disease prevalence has doubled in the past 25 years, emphasising the importance of awareness and early detection.

How do doctors diagnose movement disorders?

Healthcare providers diagnose movement disorders through comprehensive neurological examinations, detailed medical histories, and observation of movement patterns. Diagnostic testing may include brain imaging, genetic analysis, blood tests, and specialised panels. The diagnostic process requires careful evaluation to distinguish between different movement disorder types and develop appropriate treatment plans.

Can stress cause involuntary movements?

Stress can trigger or worsen certain types of involuntary movements, including tics, tremors, and muscle spasms. However, stress alone rarely causes primary movement disorders. Chronic stress may exacerbate existing neurological conditions or contribute to functional movement disorders. Managing stress through relaxation techniques, exercise, and adequate sleep can help reduce symptom severity.

Which doctor should I consult for movement disorders?

Start with your primary care physician, who can perform initial assessments and provide referrals to neurologists specialising in movement disorders. Movement disorder specialists have additional training in diagnosing and treating these complex neurological conditions. They can offer comprehensive evaluation, advanced treatment options, and ongoing management strategies tailored to your specific condition.
