Drug abuse is a serious problem, which is capable of not only causing death to the one using it, but create a havoc in the lives of those who are associated with that person too. There have been plenty cases, whether it is Matthew Perry or the recent death of Liam Payne, which is in trial currently.

It is also a problem in the US and is emerging as one of the health concerns that could destroy families and society. One of the most alarming aspects of drug abuse is also its impact on public safety as well as increased crime rates. Drugs also take a heavy toll on healthcare systems as emergency departments frequently encounter cases of drug overdoses, which puts the burden on medical professional who have the strain the limited resources available.

There are also long-term health impact due to drug abuse, which includes organ damage, infectious disease, mental health disorders and rise in healthcare cost.

Are there any specific drugs which are most abused in US?

Yes. There are commonly used drugs, which also includes prescribed painkillers like oxycodone, hydrocodone, and fentanyl, as well as illicit substances like heroin. As per recent data, opioid abuse has also reached alarming levels which has affected millions of Americans.

Here are the most abused drugs in the US:

Stimulants

They are used to increase alertness, attention, and energy. They also have a high potential for abuse due to the euphoric and performance enhancing effects. Cocaine and methamphetamine are notable stimulants frequently abused in the US. As per 2019 data, 10.3 million people reported to misuse stimulants in the previous year.

Depressants

These substances are used to slow down brain activity and induce relaxation. Benzodiazepines is one of the commonly prescribed medicine. Around 4.8 million individuals in the US have misused this drug.

Other misused drugs and its affects on the health:

Opioids:

It could lead to slow breathing and heart rate. It can also increase the risk of overdose and respiratory failure, constipation and a weakened immune system.

Stimulants:

It can elevate heart rate and blood pressure. It could also increase body temperate and lead to an irregular heartbeat. Furthermore, one can experience loss of appetite and weight loss.

Cannabis:

This can alter perception and coordination. People who consume it often have red eyes and a dry mouth. This can increase appetite, sometimes the "munchies" can reach to a point of no return and it could impair memory and cognitive function.

Benzodiazepines:

It could lead to sedation and drowsiness and an impaired coordination and balance. There also could be memory problems and confusion, along with respiratory depression, when combined with other depressant substance.

Alcohol:

This could lead to slurred speech, impaired condition, poor judgment and decision-making, liver damage and cirrhosis and an increased risk of accidents and injuries, which is the 3rd most leading cause of death in the US.

Additional Negative Impact: Social and psychological

Substance abuse impairs job performance and reliability, leading to frequent absenteeism, reduced productivity, and even job loss. This further leads to financial instability, strained relationships, and a cycle of dependency.

World Parkinson’s Day is observed every year on April 11 to raise awareness about the progressive, neurodegenerative movement disorder caused by the loss of dopamine-producing brain cells.

People suffering from Parkinson’s face problems in motor movement, tremors, stiffness, and impaired balance. As symptoms progress, people may have difficulty walking, talking, or completing other simple tasks.

The condition primarily affects people over 60, but is now increasingly being seen in young adults. Apart from motor loss, the disease also causes cognitive decline, depression, anxiety, and swallowing problems.

World Parkinson's Day 2026: Origin

Parkinson's Day is observed on the day that marks the birthday of James Parkinson (born in 1755). The London-based doctor was the first to describe Parkinson as a medical condition in 1817, in his famous ‘Essay on the Shaking Palsy’. In 1997, the day was officially established by the European Parkinson’s Disease Association.

World Parkinson's Day 2026: Theme

The theme of World Parkinson's Day 2026 is "Bridge the Care Gap." It reflects a critical challenge that persists despite advances in medical research: many people living with Parkinson's still lack consistent access to specialist care, affordable treatment, and integrated support systems.

The day also aims to raise awareness about neurodegenerative diseases by educating the public about Parkinson's symptoms, causes, and available care.

Global Burden of Parkinson’s

Parkinson's disease affected 11.9 million people in 2021 and will affect 25.2 million people globally by 2050, representing an alarming 112 per cent rise.

According to a 2025 study released by The BMJ, this rise is mainly due to population aging and hence ranks as one of the most rapidly growing neurological disorders based on prevalence and disability. This alarming increase necessitates immediate global health interventions, research innovation, and policy reform to counteract its effects on people and health systems globally.

In addition, lifestyle differences, genetic susceptibility, and environmental exposures can also lead to regional variation in prevalence.

What Happens To Your Brain In Parkinson's Disease?

Parkinson's Disease affects various brain regions, but the primary symptoms arise from the degeneration of neurons in the substantia nigra, a region near the brain's base. This area is crucial for producing dopamine, a chemical messenger essential for smooth and purposeful movement. Research indicates that by the time Parkinson's symptoms become evident, patients have typically lost 60 to 80% or more of these dopamine-producing neurons.

Additionally, individuals with Parkinson’s disease experience a reduction in nerve endings that produce norepinephrine, a neurotransmitter responsible for regulating many involuntary bodily functions, such as heart rate and blood pressure. This loss may account for some non-movement-related symptoms of Parkinson’s, such as fatigue and fluctuations in blood pressure.

How to Prevent Parkinson's

Though there is no cure for Parkinson's disease yet, studies indicate that some lifestyle elements have the potential to shape its incidence and progression.

  • Physical Activity – Engaging in regular exercise has been linked to a reduced risk of Parkinson’s, potentially due to its neuroprotective effects.
  • Diet and Nutrition – A balanced diet rich in antioxidants, omega-3 fatty acids, and plant-based nutrients may support brain health.
  • Environmental Factors – Exposure to pesticides, heavy metals, and air pollution has been associated with an increased risk, suggesting a need for improved public health measures.

Why Regular Scans Are Crucial for Liver Cancer Patients: Doctors Explain

Updated Apr 11, 2026 | 12:18 AM IST

SummaryIt is not very common for a cyst to recur after liver cancer treatment. Sometimes, what appears to be a recurrent cyst may actually be an infection or a blockage. Regular follow-up is important, said doctors.

Indian Actress Dipika Kakkar, battling liver cancer, underwent another surgery last month for a 1.3 cm cyst that reappeared.

Best known for her role as Simar Bhardwaj in the hit TV show Sasural Simar Ka, Dipika underwent a major tumour-removal surgery in June 2025. She also undertook chemotherapy

In her latest vlog, Dipika shared that the unexpected recurrence has left her feeling anxious and overwhelmed as doctors evaluate the next course of treatment.

"The recurrence that happened with the 1.3 cm cyst has shaken me. I am a little scared now that it shouldn't happen again. I have started dieting, but I feel anxious," she said.

HealthandMe spoke to health experts to understand why cysts recur in liver cancer patients and how it's important to keep monitoring them.

According to health experts, a biannual liver scan is imperative, and it can detect signs of cysts.

“Simple cysts less than 2-3 Cm can be observed with repeat scans every 6 months to 1 year. Suspicious or malignant cysts need surgical resection and oncological treatment based on the histopathology and patient condition,” Dr Manjunath NML, Sr Consultant, Surgical Oncology and Robotic Surgeon, HCG Cancer Hospital, K R Road, Bengaluru.

What Are Liver Cysts? How It's Linked To Cancer

Liver cysts are like bags that are filled with fluid. They are usually not cancer. Most people who have liver cysts do not get cancer.

However, just because one has a cyst, it does not mean it's cancer.

“Cysts in the liver are typically harmless and unrelated to liver cancer. However, unusual types of cysts may suggest malignant changes that need further examination, particularly among risk groups,” Dr. Govind Nandakumar, Consultant – Gastrointestinal Surgery, Manipal Hospitals Hebbal, told HealthandMe.

The experts noted that cases of recurring cysts related to liver cancer are uncommon. But they occur because of

  • the presence of cancerous cells,
  • regrowth of the organ,
  • chronic conditions like cirrhosis.
“It is not very common for a cyst to recur after liver cancer treatment. If a cyst does return, it could indicate that the liver is not healthy. Sometimes, what appears to be a recurrent cyst may actually be an infection or a blockage. Regular follow-up with a doctor is important so that any issues can be detected early. If a problem is identified in time, it can be treated, and more serious complications can be prevented,” Dr. Hemkant Verma, Oncology Consultant, Shardacare Healthcity, to HealthandMe.

Are There Early Warning Signs Patients Should Watch For?

Many liver cysts do not cause any problems in the early stages. That is why regular check-ups with a doctor are important. If a cyst grows or becomes problematic, symptoms may begin to appear. These can include

  • abdominal pain,
  • bloating,
  • nausea,
  • weight loss,
  • yellowing of the skin,
  • fatigue.
“Liver cysts are fluid-filled cavities in the liver that may present as single or multiple lesions. The majority (around 95 per cent) are benign, while about 5 per cent may be cancerous. In many cases, the exact cause of their formation is unknown, and they may also be associated with conditions such as polycystic kidney or ovarian disease. Most patients are asymptomatic, and these cysts are often detected incidentally during routine scans,” said Dr. Manjunath, told HealthandMe.

Is Recurrent Cysts A Cause Of Worry?

Recurrent cysts can be effectively managed and treated over time. The recurrence does not necessarily imply the progression of the condition itself; however, more tests may be required to determine whether cysts are malignant or benign.

“Cysts with thick walls, septations inside, and solid components in them are more likely to be cancerous. If the cysts are large, they cause symptoms like pain, distension, and obstruction of the bowel or biliary tract,” Dr Manjunath said.

The experts explained that diagnosis can be achieved by scans like ultrasonography, Computerized Tomography CT or Magnetic Resonance Imaging (MRI). Suspicious cysts must be checked via biopsy to confirm malignancy.

While suspicious or malignant cysts require surgical resection and oncological treatment, symptomatic cysts, even if benign, may also require removal.

However, if a liver cyst is detected without suspicious features and is asymptomatic, it usually does not require any intervention, Dr. Manjunath noted.

Beyond The Tremor: Why Early Signs Of Parkinson’s Are Most Critical

Updated Apr 10, 2026 | 10:00 PM IST

SummaryThere is no single ‘Parkinson’s diet,’ but certain food choices can help manage symptoms and overall well-being. A balanced diet rich in fruits, vegetables, and whole grains supports general health and may help reduce inflammation.
Beyond The Tremor: Why Early Signs Of Parkinson’s Are Most Critical

What if the body whispers long before it screams? For many living with Parkinson’s disease, the earliest signs are not the tremors, but quieter changes, such as a diminished sense of smell, disrupted sleep, or gut problems. The challenge is that we are conditioned to look for the disease only once it becomes visible.

Parkinson’s disease, commonly referred to as a movement disorder, progresses slowly due to the destruction of the nerve cells in the brain.

To understand Parkinson’s disease, think of the brain as a command center where certain nerve cells produce dopamine, a chemical messenger that helps coordinate smooth movement. As these dopamine-producing cells gradually deteriorate, the brain’s signalling system gets disturbed, leading to slower movements, mistaken for normal ageing.

The majority of patients experience subtle early signs much before diagnosis, including a reduced sense of smell, sleep disturbances like insomnia, and persistent digestive problems like constipation. In these cases, timely intervention can reduce movement disability by roughly 40 percent.

Parkinson’s Treatment

Conventional treatment focuses on medications that boost dopamine levels, but over time, their effectiveness may decline. When drugs are no longer sufficient, doctors may recommend Deep Brain Stimulation (DBS), a surgical approach that works like a pacemaker for the brain and uses chest-connected electrodes to reset faulty signals causing stiffness and tremors.

Unlike fixed traditional stimulation, the advanced Adaptive DBS (aDBS) listens to brain signals in real-time to adjust therapy automatically. Its single threshold mode reacts instantly, boosting stimulation the moment brain signals hit a specific limit and turns it off just as fast once they improve.

Alternatively, its double threshold mode keeps stimulation steady within the safe zone," making only gradual tweaks if signals cross upper or lower limits. This smart system mimics the body’s natural rhythm to provide fluid symptom control while preventing overstimulation, ultimately helping you reclaim more "good" time and independence.

Parkinson’s Diet

There is no single ‘Parkinson’s diet,’ but certain food choices can help manage symptoms and overall well-being. A balanced diet rich in fruits, vegetables, and whole grains supports general health and may help reduce inflammation.

Plant-based flavonoids, present in berries, citrus fruits, and broccoli, which have antioxidant effects, can help protect brain cells from damage. Drinking enough water can support digestion and prevent dehydration.

Ultimately, small, consistent dietary choices, combined with medical guidance, can make a meaningful difference in managing symptoms.

Parkinson’s disease is a journey, and the earlier the signs are recognized, the better the condition can be managed. If you or a loved one is experiencing persistent changes in sleep, smell, or movement, do not wait for the symptoms to become overwhelming. Consulting a neurologist is the first step toward taking back control of your health.
