Though rare, Angelman syndrome brings many insights into what can be deeply complex about genetic disorder conditions and profound effects on individuals and families. Originally described in 1965 by Dr. Harry Angelman, the condition would soon become one of the prominent areas of interest in medical science, advocacy, and awareness.

Actor Colin Farrell has made significant efforts advocating for awareness around Angelman syndrome. His son, James, was diagnosed with the condition at 2.5 years old, having been initially misdiagnosed with cerebral palsy. Farrell's advocacy draws attention to the problems parents have to face while navigating misdiagnoses and limited resources. He has since started initiatives to support families, especially because many state-level services end once the individuals with disabilities turn 21.

Below, we discuss the causes, symptoms, treatments, and the lives of individuals and caregivers living with Angelman syndrome.

What is Angelman Syndrome?

Angelman syndrome (AS) is a neurogenetic disorder affecting around 1 in 12,000 to 1 in 24,000 individuals. Due to its similarity with other developmental disorders, including autism and cerebral palsy, this condition is not easily diagnosed. The syndrome impacts both males and females equally, but they experience various delays in their development, seizure episodes, and typical behaviors that are accompanied by constant laughter and happiness.

What causes Angelman Syndrome?

Angelman syndrome results from mutations in the UBE3A gene on chromosome 15. This gene is crucial for brain development because it encodes a protein necessary for neuronal function. Normally, one copy of the UBE3A gene from each parent is active throughout the body. However, in some parts of the brain, only the maternal copy is active.

When the maternal copy is missing, mutated, or otherwise inactive, Angelman syndrome occurs. The majority of cases result from spontaneous mutations, but about 3-5% are inherited. Interestingly, in approximately 10% of cases, the exact cause cannot be pinpointed.

Early Signs and Symptoms

Major symptoms or manifestations of Angelman syndrome start manifesting in the lives of parents when the child is between 6-12 months old. These early developmental delays, such as the child's failure to sit up or babble, would also warrant further investigation. As time progresses, other symptoms start to manifest themselves:

• Walker, has trouble walking, balance, or stiff-legged gaits.
• Little to no speech and heavily depends on non-verbal clues like gestures.
• Frequent laughter, hand flapping, and hyperactivity.
• Often starting between the ages of 2 and 3, seizures are frequent and sometimes lifelong.
• Large mouth, deep-set eyes, prominent chin.

Most children are symptom-free at birth, and delays in diagnosis are common, with children often misdiagnosed as having cerebral palsy or autism.

How is Angelman Syndrome Diagnosed?

The diagnosis of Angelman syndrome is established by a combination of clinical evaluation and genetic studies.

• Chromosome Analysis: It studies the length, form, and number of chromosomes.
• DNA Methylation Testing: It determines whether both copies of the UBE3A gene are active.
• Fluorescent In Situ Hybridization (FISH): It detects missing or abnormal chromosomes.
• UBE3A Sequencing: It identifies mutations in the maternal copy of the gene.

These tests confirm the condition, bringing clarity and a path forward for treatment and management.

Living with Angelman Syndrome

There is no cure for Angelman syndrome, but early interventions improve and enhance the quality of life for patients. Treatments are merely aimed at symptom management and developmental support. This includes the use of:

Anti-epileptic medications to control seizures

Therapy improves mobility as well as reduces joint stiffness

Speech and Occupational therapy improves communication skills and daily living function

Behavioral Therapy manages hyperactivity and attention deficit.

Despite the challenges, many individuals with Angelman syndrome lead fulfilling lives. With proper support, adults can learn basic household tasks and, in some cases, secure supervised employment. Group homes provide a nurturing environment for adults who cannot live independently, emphasizing a sense of community and belonging.

What are the Risk Factors and Complications

There are no risk factors established except the possible presence of a family history for Angelman syndrome, a very rare genetic disorder. Such children often develop various complications requiring management. Common issues include feeding, especially at the infancy level. This might include sucking and swallowing problems leading to the requirement of specialized feeding methods. Sleep disturbances, including frequent waking and decreased need for sleep, can be a significant challenge in daily life and may be treated with behavior therapy or medication. Hyperactivity is also a common problem in younger children with Angelman syndrome, although it often decreases with age, making it easier to adapt over time.

Research into Angelman syndrome is ongoing, with studies on gene therapy and other potential treatments. Advocacy efforts, combined with early diagnosis and intervention, bring hope to families around the world.

Understanding Angelman syndrome is a step toward better care, inclusivity, and support for those affected. With increased awareness and advancements in treatment, individuals with Angelman syndrome can thrive in environments tailored to their unique needs.

California made it news for a disease that has no vaccination. This is the human metapneumovirus or the HMPV. While some of the symptoms of this virus are similar to that of any common cold or influenza like cough, fever, nasal congestion or shortness of breath, there are several symptoms that are unique to the disease.

Unique Symptoms Of HMPV - The Virus Without Vaccine

Unlike mild common colds, HMPV often presents with a high-grade fever, particularly in children. Some of the other symptoms also include persistent coughing, including dry or productive and may persist for a long duration.

Furthermore, it could cause wheezing, difficulty in breathing, which could also lead to severe lower respiratory tract illness like bronchiolitis or pneumonia. In children and older adults, it could also cause severe or often fatal bronchiolitis or rapid-onset pneumonia.

In infants, it could also exhibit irritability, poor feeding, or dehydration.

Other symptoms, which could resemble common cold like symptoms are:

• cough
• fever
• sore throat
• runny or stuffy nose
• body ache
• headache

What Is Happening In California?

As per the public database WasterwaterScan Dashboard, high levels of HMPV were detected across Northern California cities. The highest levels were reported in Redwood City, whereas elevated levels were found in San Francisco Bay Area and Napa's Wine Country. What's more dangerous is that this virus is without a vaccine.

The good news is that in other parts of country HMPV remains lower. However, the Centers for Disease Control and Prevention (CDC) noted that data from October 2025 shows the cases are trending up, especially during winter and spring.

Dr. Matthew Binnicker, director of the Clinical Virology Laboratory at Mayo Clinic, as reported by The Independent said, "In the late winter, early spring, it can account for five percent to 10 percent of all the respiratory infections that we diagnose in the United States. So it's definitely out there." Experts explain that other viruses like HMPV or influenza get a chance when COVID is quieter.

What Is HMPV - The Virus Without Vaccine?

HMPV was first discovered in 2001 and is part of the Pneumoviridae family along with the Respiratory syncytial virus (RSV).

HMPV most likely spreads from an infected person to others through:

• the air by coughing and sneezing
• close personal contact, such as touching or shaking hands
• touching objects or surfaces that have the viruses on them, then touching the mouth, nose, or eyes

In the US, HMPV circulates in predictable patterns each year, typically beginning in winter and lasting through spring.

Who Are At Risk Of HMPV?

People at risk include:

• elderly people
• children
• people with comorbidities

"The HMPV is not deadly, and there is no evidence of mortality or a severe transmission rate," former Indian Council of Medical Research (ICMR) scientist, Dr. Raman Gangakhedkar, told IANS, during the virus's outbreak in India in 2025.

“The virus may cause pneumonitis-like illness, but the mortality rates are almost unknown so far. HMPV has a global prevalence of about 4 per cent,” he added.

Smoking has been long recognized as one of the worst habits a person can have, and Dr Jeremy London agrees with this statement. Dr. London, a cardiovascular surgeon, in a recent interview with Mel Robbins revealed that his number one advice as a heart doctor is to avoid smoking.

“I cannot come up with one single thing that does as much damage to every organ in the body as smoking cigarettes. And look, it's incredibly addictive and I know that and I pass no judgment because I know how difficult it is.”

He explained that in his practice he has dealt with chronic smokers for years and still believed that it is the single most dangerous thing one can do to themselves.

How Does Smoking Affect Other Organs?

Emphasizing how this one habit affects all organs in our body, Dr London mentioned the well-known link between lung cancer and smoking.

However, there are many more chronic diseases associated with the rest of the body that can develop due to smoking apart from lung conditions, according to the American Lung Association.

Here is what you should keep an eye out for:

Lung Cancer

Smoking is the leading cause of lung cancer, accounting for nearly 90 percent of all cases. Although medical treatments have improved, the five-year survival rate remains low. Quitting is the most effective way to lower your risk of this deadly disease.

Chronic Obstructive Pulmonary Disease

Other Cancers

Fasting for three hours before bed can significantly improve heart health and reduce the risk of coronary artery disease (CAD) as well as other chronic conditions, an Arteriosclerosis, Thrombosis, and Vascular Biology study suggests.

While many believe that diet plans such as intermittent fasting or time-restricted eating can help reduce their weight, researchers at Northwestern University have found that not eating three hours before going to sleep can reduce overnight blood pressure by nearly four percent, heart rate by five percent and strengthen overall heart rhythms.

This can help reduce overall strain on the heart which lowers risks for conditions like hypertension and CAD. Additionally, the scientists also discovered a drop in blood sugar levels, improved glucose tolerance and insulin sensitivity.

Participants who underwent glucose tests also showed better insulin release which tend to stabilize during the day. Additionally, an improved heart rate also lowered nighttime cortisol, which helped in metabolic balance.

Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine and chief of sleep medicine in the department of neurology at Feinberg and corresponding author said of the results: "It's not only how much and what you eat, but also when you eat relative to sleep that is important for the physiological benefits of time-restricted eating."

The study authors also noted: "Extending overnight fasting duration by three hours in alignment with sleep improved cardiometabolic health in middle-aged/older adults by strengthening coordination between circadian- and sleep-regulated autonomic and metabolic activity.

"This sleep-aligned time-restricted eating approach represents a novel, accessible lifestyle intervention with promising potential for improving cardiometabolic function."

Coronary Artery Disease: The Silent Killer

Despite being as a common heart disease, coronary artery disease (CAD) develops over years and has no clear signs and symptoms apart from a heart attack. The illness begins due to a buildup of fats, cholesterol and other substances known as plaque in and on the artery walls.

Over time, this can cause narrowing or blockage of the coronary arteries and block the supply of oxygen-rich blood to heart which can lead chest pain (angina), shortness of breath and ultimately, heart attacks.

Typically, those above the age of 45, having a biological family member with heart disease, lack of sleep, smoking, consuming saturated fats along with other autoimmune diseases such as lupus and rheumatoid arthritis can increase the risk of developing CAD.

Treatment options may include medicines and surgery. Eating a nutritious diet, getting regular exercise and not smoking can help also prevent CAD and the conditions that can cause it.

Nearly one in 10 Indian adults suffer from CAD and about two million people die from the disease annually. Apart from this, about 18 to 20 million American adults aged 20 and older are also affected about the disease.

Strokes: A Rising Crisis In India

One in seven stroke patients in India are young adults aged below 45 years, with hypertension leading as the major risk factor, according to a study by the Indian Council of Medical Research (ICMR).

The Global Burden of Disease Study 2021 identified hypertension, air pollution, tobacco smoking, high cholesterol, increased salt intake, and diabetes as the leading risk factors of stroke.

Incidence of stroke is increasing significantly in low- and middle-income countries (LMICs), especially in India, due to population growth, aging, and greater exposure to risk factors.
