Introduction: Why Do Old People Shake? This common query explores the various reasons behind tremors in older adults, ranging from benign causes to more serious underlying conditions. At WHY.EDU.VN, we aim to provide clear, accessible explanations and expert insights to help you understand and address this concern. Delving into the nuances of geriatric tremors, neurological conditions, and involuntary movements.
1. Tremors and Aging: An Overview
Shaking in elderly populations can stem from various factors, including benign issues that resolve independently, or underlying diseases. While not all older adults experience shaking, those with a family history of movement disorders are at a higher risk. Age-related tremor is under study, with evidence suggesting neurodegeneration as a potential cause, according to the National Center for Biotechnology Information.
2. Common Causes of Tremor in the Elderly
Identifying the causes of shaking hands in elderly populations can be complex. Tremors aren’t exclusive to the elderly; they can occur at any age due to factors like low blood sugar.
2.1. Essential Tremor
Essential tremor is a prevalent movement disorder affecting around 5% of the global population. This condition causes involuntary shaking in the hands, head, voice, torso, or legs, predominantly in individuals over 65. Essential tremor can significantly impair daily activities like eating and drinking, and its severity tends to increase over time. While there is no cure, treatments are available to manage the symptoms.
2.2. Parkinson’s Disease
Parkinson’s disease is frequently diagnosed in individuals over 60 and has doubled in prevalence over the past 25 years, according to the World Health Organization. Tremors associated with Parkinson’s disease are caused by the degeneration of nerve cells in the brain, leading to reduced muscle control and decreased life expectancy. The American Parkinson Disease Association reports that 80% of Parkinson’s patients experience involuntary movements.
2.3. Huntington’s Disease
Huntington’s disease is an inherited condition that causes a decline in brain function and reduces life expectancy, with symptoms typically appearing between 30 and 50 years of age. The disease is characterized by involuntary movements of the arms, legs, head, face, and upper body, as well as cognitive decline.
2.4. Multiple Sclerosis (MS)
Multiple sclerosis is a chronic autoimmune disease that affects the central nervous system, disrupting communication between the brain and the body. MS can cause various symptoms, including numbness, stiffness, vision problems, and shaking hands. It most commonly affects individuals aged 20 to 40. There is no cure, but medications and lifestyle changes can help manage symptoms and flare-ups.
2.5. Stroke
A stroke occurs when blood flow to the brain is blocked or interrupted, leading to potential brain damage, disability, or death. Damage to the cerebellum or basal ganglia after a stroke can result in tremors, including shaking hands. However, this is a rare occurrence, with 28% of patients experiencing resolution of tremors within one year, and 64% experiencing partial resolution.
2.6. Cerebral Palsy (CP)
Cerebral palsy is a motor condition that affects movement and muscle tone. Symptoms vary but often include stiff muscles, exaggerated reflexes, lack of balance, and tremors. CP is typically diagnosed before the age of 5, although late diagnoses are possible as symptoms become more pronounced.
2.7. Caffeine Toxicity
Excessive caffeine intake can induce tremors, along with symptoms like anxiety, restlessness, agitation, stomach issues, irregular heartbeat, and insomnia. Caffeine triggers the release of adrenaline, which can cause shaking.
2.8. Pharmaceutical Side Effects
Certain prescription drugs can cause tremors as a side effect. Common culprits include:
- Epinephrine and norepinephrine
- High blood pressure drugs
- Alcohol
- Antivirals
- Antibiotics
- Antidepressants
- Stimulants
- Mood stabilizers
- Immunosuppressants
- Asthma medication
- Seizure medication
- Cancer treatments
2.9. Overactive Thyroid
An overactive thyroid gland, or hyperthyroidism, can cause the body to be in a constant state of overdrive. This overstimulation of the nerves can lead to hand tremors, along with symptoms such as a racing heart, weight loss, increased appetite, perspiration, exhaustion, and heat intolerance. According to Harvard Health, millions suffer from this condition.
2.10. Alcohol Abuse or Withdrawal
Tremors can result from excessive alcohol consumption and alcohol withdrawal. These tremors may start within 10 hours after the last drink and can persist for weeks. Recovering alcoholics should only reduce their alcohol intake under the guidance of a healthcare provider. Rehab and detox programs offer medications to manage tremors and other withdrawal symptoms.
2.11. Hypoglycemia
Hypoglycemia, or low blood sugar, deprives muscles and nerves of their energy source, leading to hand tremors. Additional symptoms include sweating, hunger, and anxiety due to the release of hormones like epinephrine and norepinephrine. The Hormone Health Network provides further information on this condition.
2.12. Anxiety
Anxiety can trigger tremors in the elderly. These tremors, also known as psychogenic tremors, occur when the body prepares to react to danger, causing muscles to twitch or shake. Psychogenic tremors are linked to stress, anxiety, depression, or underlying psychiatric issues like PTSD.
3. Genetic Factors in Elderly Tremors
Tremors can be hereditary. About 50% of all essential tremor cases are believed to be caused by genetic factors. Essential tremor is thought to be an autosomal dominant trait. If one parent has an altered gene for essential tremor, there is a 50% chance of developing the disorder. Inherited essential tremor often appears earlier in life compared to other forms.
4. Different Types of Tremors
The National Institute of Neurological Disorders and Stroke categorizes various types of tremors, ranging from temporary shaking to long-term movement disorders.
4.1. Action Tremor
Action tremors are linked to essential tremor. These tremors, including postural, isometric, and kinetic tremors, occur during voluntary muscle contractions.
- Postural tremor: Occurs when holding a position against gravity, like extending arms.
- Kinetic tremor: Occurs during voluntary actions, such as reaching for an object.
- Isometric tremor: Occurs during voluntary muscle contraction without movement, like holding a book.
4.2. Physiologic Tremor
Everyone experiences physiologic tremor, which is usually unnoticeable and results from normal bodily functions like heartbeats and blood flow.
4.3. Enhanced Physiologic Tremor
Enhanced physiologic tremor is more noticeable than typical physiologic tremor. It is usually temporary and caused by hypoglycemia, alcohol, or drug reactions. This type of tremor can be reversed by addressing the underlying cause.
4.4. Cerebellar Tremor
Cerebellar tremor occurs at the end of purposeful movements, such as pressing a button. It is often caused by brain damage from a stroke, multiple sclerosis, or chronic alcoholism.
4.5. Psychogenic Tremor
Psychogenic tremor is triggered by stress, anxiety, depression, or psychiatric issues like PTSD. This tremor can affect the hands and other body parts, increasing during stress and decreasing with distraction.
4.6. Parkinsonian Tremor
Parkinsonian tremor is a common symptom of Parkinson’s disease, though not all individuals with Parkinson’s experience it. It typically occurs at rest in one or both hands. Tremors can also affect the head, face, or legs. While it often starts on one side of the body, it can spread to both sides as the disease progresses.
4.7. Orthostatic Tremor
Orthostatic tremor is rare and characterized by very fast shaking, often imperceptible to the naked eye. Individuals with orthostatic tremor may experience imbalance or unsteadiness. The cause is currently unknown.
5. Impact of Shaking on Older Adults
Tremors can significantly affect the quality of life for older adults. They impair the ability to perform daily tasks like eating, drinking, walking, and talking. Tremors can also negatively impact mental health, causing feelings of discouragement and inadequacy, and threaten independence.
6. Treatment Options for Elderly Tremors
Elderly tremors can be challenging to manage. Depending on the type of tremor, various treatments are available to effectively manage symptoms. Consulting with a healthcare provider is crucial to determine the most suitable treatment plan.
6.1. Lifestyle Changes
Making small lifestyle changes can significantly improve tremor symptoms. Modifying your diet by reducing or eliminating caffeine, nicotine, and alcohol can help. Managing stress and anxiety through relaxation exercises like deep breathing and meditation can also mitigate unwanted thoughts and reduce tremor severity.
6.2. Medication
Medications such as beta-blockers, anticonvulsants, tranquilizers, and botox are commonly prescribed to reduce the frequency and amplitude of tremors. However, medication may not be suitable for everyone, and finding the right one may require trial and error. Side effects and tolerance can also be concerns.
6.3. Surgery
Surgery may be considered for severe, debilitating tremors when other treatments are ineffective. Two surgical procedures are used to treat essential tremor:
- Deep Brain Stimulation (DBS): Delivers electrical pulses to specific brain areas using a neurostimulation device implanted under the collarbone.
- Focused Ultrasound: Uses magnetic resonance imaging (MRI) to pinpoint the tremor’s origin in the brain, then applies high-intensity sound waves to target and disrupt the affected tissue.
Eligibility for these surgeries depends on meeting certain criteria, and they carry risks and require a recovery period.
6.4. Cala TAPS Therapy
