Tardive dyskinesia – Causes, symptoms, and management

Tardive dyskinesia (TD) is a complex neurological disorder characterized by involuntary and repetitive movements of various body parts, most commonly the face, neck, and trunk. These abnormal movements often occur as a side effect of certain treatments. Other factors can contribute to its development as well. It has a multitude of causative factors. Understanding these causes is vital for healthcare providers and individuals alike, ultimately aiming to mitigate the impact of this challenging neurological disorder.

Treatment-induced tardive dyskinesia
The primary and most widely acknowledged cause of tardive dyskinesia is the prolonged use of certain treatment options. These treatments are typically prescribed to manage psychiatric conditions like schizophrenia, bipolar disorder, and severe depression. Unfortunately, while they can be effective in treating these conditions, long-term use can lead to the development of TD.

Other risk factors
While treatment use is the dominant cause, several additional risk factors can contribute to an individual’s susceptibility to tardive dyskinesia:

  • Age: Older adults are at a higher risk of developing TD. This may be due to age-related changes in brain structure and function, making them more vulnerable to treatment effects.
  • Genetics: Genetic factors can influence an individual’s likelihood of developing TD. Some people may have a genetic predisposition that makes them more susceptible when exposed to triggering treatment options.
  • Duration of treatment usage: The longer an individual takes the treatment with the potential to cause TD, the greater their risk. This makes it crucial for healthcare providers to regularly evaluate the necessity of continued medication and explore possible alternatives.
  • Treatment type: These include treatment options for nausea, vomiting, and other gastrointestinal issues.

Symptoms of tardive dyskinesia
Recognizing the symptoms of TD is crucial for early diagnosis and intervention, which can help manage the condition more effectively. Exploring its symptoms helps show what individuals and healthcare providers should watch out for.

  • Involuntary facial movements: One of the hallmark signs of TD is the presence of involuntary facial movements. These movements can manifest in various ways, and they are as follows:
    • Grimacing: Patients may exhibit grimacing, characterized by involuntary contractions of facial muscles. This can lead to awkward or contorted facial expressions.
    • Lip smacking or puckering: Repetitive lip smacking, puckering, or pursing is another common symptom of TD. These movements can occur without the individual’s control.
    • Tongue protrusion: Involuntary tongue movements, such as sticking the tongue out or thrusting it against the inside of the cheek, are frequent in TD cases.
    • Blinking and eye movements: Uncontrollable blinking or rapid, irregular eye movements may occur, affecting vision and causing discomfort.
  • Involuntary movements of the limbs: Tardive dyskinesia can also affect the limbs, causing repetitive and involuntary movements. These can include the following:
    • Finger tapping: Individuals may exhibit rapid, repetitive tapping of the fingers against each other or another surface.
    • Toe-tapping or foot shuffling: Involuntary toe-tapping or foot shuffling may occur, often resulting in difficulty walking or maintaining balance.
    • Arm or leg jerks: Sudden jerking movements of the arms or legs can be a symptom of TD.
  • Involuntary movements of the trunk and neck: In some cases, tardive dyskinesia extends to the trunk and neck, leading to the following:
    • Twisting or turning of the trunk: Individuals may experience twisting or turning of the trunk, causing discomfort and postural difficulties.
    • Neck movements: Involuntary neck movements, such as repetitive tilting or shaking, can be observed.

Other symptoms
Here are a few other symptoms to know about:

  • Vocalization symptoms: TD can also affect vocalization, resulting in grunting, snorting, chirping, or whistling noises without the individual’s control.
  • Interference with daily activities: One of the most challenging aspects of tardive dyskinesia is how it interferes with daily life. The involuntary movements and vocalizations associated with TD can disrupt speech, eating, and other essential activities. These disruptions often lead to significant social and emotional distress for individuals affected by TD.

Tardive dyskinesia presents a range of symptoms, primarily characterized by involuntary and repetitive movements affecting various body parts. Recognizing these symptoms, understanding the risk factors, and seeking early medical intervention are crucial to managing this challenging neurological disorder. Individuals experiencing these symptoms or healthcare providers working with such patients should prioritize a thorough evaluation to ensure an accurate diagnosis and effective management strategies.

Remedies to deal with tardive dyskinesia
While there is no definitive cure for TD, several remedies and strategies can help manage its symptoms and improve the quality of life for affected individuals. Various approaches are used to address TD, ranging from treatment adjustments to lifestyle changes and therapy.

  • Lifestyle modifications: Lifestyle changes can also play a significant role in managing TD symptoms:
    • Avoid triggering factors: Reducing or eliminating factors that exacerbate TD symptoms is crucial. These may include caffeine and illicit substances, which can worsen the condition.
    • Stress management: Stress can exacerbate TD symptoms. Relaxation techniques such as deep breathing, meditation, or yoga can help individuals better cope with stress.
    • Adequate sleep: Ensuring proper sleep hygiene and obtaining sufficient rest can positively impact TD symptoms.
  • Physical and occupational therapy: Physical and occupational therapy can be valuable components of TD management. Physical therapy focuses on improving muscle control and mobility, while occupational therapy helps individuals develop strategies to cope with TD-related challenges in daily life.
  • Support groups and counseling: Living with TD can be emotionally challenging. Joining support groups or seeking counseling can provide individuals and their families with valuable emotional support and coping strategies. Sharing experiences with others facing similar challenges can reduce feelings of isolation and improve overall well-being.
  • Regular follow-ups: Maintaining regular follow-up appointments with a healthcare provider is essential. Monitoring the progression of TD and adjusting treatment strategies as needed ensures that the condition is effectively managed over time.

It’s important to recognize that what works best for one person may not be as effective for another. Therefore, an individualized approach to TD management is crucial. Healthcare providers should work closely with individuals to tailor treatment plans to their specific needs and preferences.

While tardive dyskinesia may not have a definitive cure, several remedies and strategies can help manage its symptoms and improve the quality of life for those affected. The key lies in early diagnosis, regular monitoring, and a multidisciplinary approach that addresses TD’s physical and emotional aspects. With the right combination of treatments and support, individuals with TD can lead fulfilling lives while effectively managing their condition.

Top 6 foods that may reduce dementia risk

Many individuals mistakenly believe that dementia is a disease, but it’s a term used to describe symptoms related to memory, social abilities, and thinking. These symptoms can be challenging to manage and can impact daily activities. However, healthcare professionals often recommend implementing a healthy meal plan as a way to improve management. If you’re interested in learning about how your food intake can reduce the risk of developing dementia, read on. What is dementia? As previously mentioned, dementia is not a specific disease. Instead, health conditions like Alzheimer’s disease are among its most frequent causes in older adults. Other known causes of dementia include damage to the blood vessels that supply nutrients to the brain, the formation of balloon-like proteins in the brain, and the breakdown of connections and nerve cells in the brain. While memory loss is one of its most recognizable signs, this symptom alone does not mean one has dementia. Most symptoms of this group of health issues can vary depending on the cause. Hence, here are some of the most common signs to look out for. Memory loss Difficulties while communicating Reasoning and problem-solving issues Poor control of movements and coordination Disorientation Confusion What are the foods that can help reduce the risk of dementia? Typically, dementia and Alzheimer’s are known to be caused by a combination of several factors, such as environmental, lifestyle, and genetic. Furthermore, developing issues such as high blood pressure, diabetes, and heart disease can contribute to cognitive decline in patients. Therefore, healthcare professionals suggest the consumption of nutrient-rich foods to reduce dementia risk as one grows older. Some of the foods that can be added to one’s meal plan are: Avocados Avocados are one of the most commonly known superfoods, which can provide the brain with the needed energy without a spike in blood sugar levels.
Avoid these 15 common shower mistakes

Avoid these 15 common shower mistakes

There is nothing a warm shower cannot resolve. Showering after a long day can be a stress reliever and enhance one’s mood instantly. It also has several other health benefits besides cleansing the body, including facilitating cold relief, boosting immunity, and relieving muscle pain. However, not bathing the right way can give rise to skin conditions such as rashes and eczema. Here are some common mistakes one should avoid while bathing and showering: Not moisturizing after a shower Wiping after a bath can reduce the body’s moisture, causing dry skin, which can lead to rashes and itching. Dermatologists recommend applying body lotion and moisturizer immediately after a shower to retain skin texture and prevent dryness. One should look for hypoallergenic moisturizers that do not have any added fragrances. Bathing in scorching hot water Scorching hot water can damage keratin cells in the skin’s outer layer. Consequently, the skin becomes dry and dehydrated. It is important to balance the water temperature before stepping into the shower. Ideally, the temperature of the water should be lukewarm. Using the wrong towel An absorbent towel that does not feel rough is ideal for wiping oneself after a shower. The most effective way to select the right towel is to check its density, measured in grams per square meter (GSM). Towels with GSMs between 400 and 550 are considered ideal for use after bathing. One should avoid towels below a GSM of 400, as these towels can be thin and rough, causing skin dryness. Moreover, towels made of superior-quality Egyptian or Turkish cotton are extremely soft and perfect for the skin. Soaping the arms and legs excessively While it is important to wash and clean one’s arms and legs, these areas typically do not collect much oil and dust. Hence, scrubbing them excessively can dry out these areas and hamper their natural texture.
15 signs of a weak immune system

15 signs of a weak immune system

The immune system is a complex network of organs, cells, and proteins that act as the body’s defense mechanism against diseases and infections. The system —the innate immune system that people are born with and the adaptive immune system, which develops due to exposure to toxins and microbes. Both parts work together to keep infection-causing germs and toxins. So, weak immunity can make the body susceptible to diseases and other health issues. High stress levels The American Psychological Association suggests that chronic stress weakens the immune system. This is because stress lowers the number of white blood cells (i.e., lymphocytes) in the body that fight infections, increasing the risk of infections such as the common cold. Persistent cold Most adults develop two to three colds per year, which usually last from 7 to 10 days. During this period, the immune system forms antibodies to fight the virus. However, if one keeps catching a cold or is dealing with common cold symptoms for a long time, it could be a sign of weak immunity. Slow-healing wounds When one develops a cut or a wound, the body immediately goes into damage control mode to stop any bleeding and regenerate skin. Immune cells in the body guide this process. However, when dealing with a weakened immune system, wounds take longer to heal. This can make one more susceptible to infections as well. Frequent infections Those with a lowered immunity are at a higher risk of contracting infections such as pneumonia, meningitis, bronchitis, and skin infections. They are also more likely to experience autoimmune disorders, organ inflammation, blood disorders such as anemia, and growth and developmental delays. According to the American Academy of Allergy, Asthma, and Immunology, some signs of weak immunity include: – Having more than four ear infections in a year – Developing pneumonia twice within a year – Dealing with chronic sinusitis or more than three episodes of bacterial sinusitis in a year Fatigue If one constantly feels tired despite getting enough sleep, it may be a sign of weak immunity.
