Many of us believe that we are great drinkers and that alcohol does not affect us as much. People who are able to drink without showing any sign of inebriation are known as social drinkers. In short, they are not addicted to alcohol but will not turn down the opportunity to have a good time! While it may seem like it doesn’t affect you, new studies suggest that it is just an illusion, even if you have high tolerance, alcohol affects your cognitive and motor functions more than you think.

The study reveals the below implications and techniques:

• Researchers used a new MRI technique to precisely measure brain electrical activity.
• By comparing brain scans before and after drinking, scientists identified specific areas affected by alcohol and how much brain activity slowed down.
• Participants were chosen to be regular social drinkers without alcohol addiction, ensuring the study focused on the effects of alcohol alone.
• MRI technology provided reliable data on brain activity changes caused by alcohol consumption.

How does the brain react to alcohol?

Think of it as the foundation for your brain's performance. When brain conductivity is high, information flows smoothly, and that helps your brain in rapid processing and response. On the other hand, low conductivity can hinder cognitive function, leading to slower thinking, impaired memory, and difficulties with coordination.

A study conducted at the Neuroscience Research Australia (NeuRA) and UNSW Science unveiled a startling connection between alcohol consumption and brain conductivity.

What is the connection between alcohol consumption and brain activity?

While many people brush off the effects of alcohol as temporary changes in behaviour, the reality is much more complex. Beyond the obvious impacts on coordination and judgment, alcohol significantly alters brain function. Alcohol dramatically slowed down brain activity, especially in areas responsible for decision-making, planning, and physical coordination. This decline was so significant that it resembled the brain changes seen in normal ageing. This means even one drink could temporarily accelerate the ageing process of your brain.

Alcohol and Brain activity: What does the study Imply?

The implications of this research are far-reaching. It provides compelling evidence that alcohol consumption has a direct and measurable impact on brain function. The discovery that alcohol can significantly reduce brain conductivity opens new avenues for understanding the neurocognitive effects of alcohol abuse and dependence. While you may not feel like alcohol is affecting you and you have a high tolerance, it most definitely changes and affects your decision-making abilities and impulse control.

Furthermore, the MRI technique employed in the study could be a valuable tool for assessing the impact of other substances on the brain and for developing interventions to mitigate alcohol-related brain damage.

Healthcare affordability was one of the major influencers of US midterm election outcomes. A recent poll revealed that more than half of US voters believe their healthcare costs have worsened under President Donald Trump's administration.

The analysis by health policy research organisation KFF was published a day after the 2026 midterm elections' results were announced. It found that 54% of midterm voters said the administration's policies had made their personal healthcare costs worse. Only 10% said their costs had improved.

Voters who said their healthcare costs had increased were more likely to support Democratic candidates. Among this group, 82% voted for Democratic candidates, compared to 16% who voted Republican.

The findings come as Democrats made significant gains in the November 3 midterms, winning control of both the House of Representatives as well as the Senate.

KFF's analysis of the 2026 Voter Poll found that Democrats had a 19-percentage-point advantage over Republicans on healthcare.

When asked which party was better equipped to handle healthcare, 49% of voters chose Democrats, compared to 30% who chose GOP.

This shows a bigger jump from the 2024 presidential election, when Democratic presidential candidate Kamala Harris had a seven-point lead over Donald Trump on the same issue.

Democrats also held a narrow advantage on the economy as 43% of voters said that they trusted the party to handle it better, compared to 37% who chose Republicans. This marked a sharp reversal from 2024, when Trump had a 10-point advantage over Harris on the economy.

The healthcare advantage was also visible among independent voters. Among independents who said Trump's policies had made their healthcare costs worse, 69% voted for Democratic candidates for Congress.

Healthcare Affordability: A Major Election Concern

Healthcare costs had emerged as a significant concern even before voters went to the polls. A separate KFF Health Tracking Poll conducted between September 16 and 21 found that six in 10 voters were worried about affording healthcare. This included 25% who were very worried and 35% who were somewhat worried.

The poll also found that 47% of voters considered healthcare costs an extremely significant issue for candidates to discuss during the midterm campaign.

Democratic candidates repeatedly highlighted healthcare affordability, criticising Republicans over the expiration of enhanced Affordable Care Act (ACA) premium tax credits and reductions in Medicaid spending included in the 2025 reconciliation law.

The enhanced ACA tax credits had helped lower insurance premiums for people purchasing coverage through the marketplaces. Their expiration raised concerns about higher insurance costs for many enrollees.

Medicaid spending reductions also became a key point of debate because of their implications for people relying on the government-funded health insurance programme.

Democrats' victory gives the party control of both chambers of Congress, creating opportunities to analyse Trump administration's healthcare policies and push for changes in insurance affordability and Medicaid. It also gives them room to bring reforms in reproductive healthcare, vaccine policies, and gender-affirming care.

However, implementing major policy changes may be difficult while Trump remains president, especially if legislation faces a presidential veto.

Pennsylvania recently announced that an unvaccinated individual tested positive for measles and died, becoming the sixth measles-associated death of 2026. The state's outbreak continues to expand as confirmed infections have now crossed 1,400 cases across 45 of its 67 counties.

The Pennsylvania Department of Health confirmed on November 4 that the resident was from Jefferson County. Officials did not release more details about the individual.

The latest death brings Pennsylvania's total to six this year. The state has recorded 1,467 confirmed measles cases across 45 counties, with 283 hospitalisations, according to its latest update.

The outbreak began in late April and has become one of the largest measles outbreaks in the United States in more than three decades.

Pennsylvania Reports Six Measles-Associated Deaths

The six deaths confirmed by Pennsylvania health officials involved residents of three counties, in which three were from Lancaster County, two from Jefferson County and one from Mifflin County.

The state also addressed reports of a separate death involving a Franklin County resident in October. However, its investigation had not found evidence meeting the criteria to classify that death as measles-associated as of November 4.

Pennsylvania's definition requires a person to have clinical evidence of measles infection and a positive laboratory test, with death occurring within 30 days since symptom begins.

There is also a difference between state and federal death counts. Pennsylvania has confirmed six deaths, while the Centers for Disease Control and Prevention (CDC) has reported three measles-related deaths in its national tally as of October 29. The CDC is working on standard definition to ascertain how measles-associated deaths are classified across states.

Pennsylvania is at the centre of a wider resurgence of measles in the country. The CDC reported 4,852 confirmed measles cases in the US as of October 29, 2026. Of these, 96% were connected to outbreaks.

The state also saw a sharp increase in vaccination activity. Healthcare providers administered more than 61,000 measles, mumps and rubella (MMR) vaccine doses in October, more than twice the usual monthly number of approximately 25,000 doses.

Measles Is Life-Threatening

Measles is a highly contagious viral infection that spreads through the air when an infected person coughs or sneezes. The virus can remain infectious in the air or on surfaces for up to two hours.

Initial symptoms include high fever, cough, runny nose and red, watery eyes. A rash usually develops several days later, beginning on the face and spreading down the body.

Although many people recover, measles can cause serious complications, including pneumonia and encephalitis, or inflammation of the brain. It can also weaken the immune system and increase vulnerability to other infections.

The MMR vaccine remains the most effective protection. Two doses are approximately 97% effective against measles.

Pennsylvania health officials recommend that people check their vaccination records and speak to a healthcare provider if they are unsure whether they have received the recommended doses.

Infants aged six to 11 months living in or travelling to areas with sustained measles transmission may also be advised to receive an early vaccine dose. This does not replace the two routine doses recommended later.

The “Make America Healthy Again” (MAHA) movement, led by Robert F. Kennedy Jr., played a key role in helping Donald Trump win the presidency in 2024. Two years later, it faces growing political opposition, with Democrats challenging the Trump administration’s healthcare policies and Kennedy’s approach to public health.

In a historic shift in the balance of power, the Democratic Party has won control of both the House of Representatives and the Senate in the 3 November 2026 midterm elections, delivering a major setback to Trump and the Republican Party. The results gives Democrats greater scope to scrutinise and reverse the administration’s healthcare agenda, including Medicaid funding, federal health agency budgets and vaccine policies.

However, their ability to reverse existing policies will be constrained by presidential veto powers and the 60 Senate votes generally needed to overcome a filibuster. The new Congress is expected to take office in January 2027.

• Healthcare costs: Rising insurance premiums, medical bills and prescription drug prices remained major concerns for voters.
• Medicaid: Funding changes and proposed work requirements raised concerns about millions potentially losing health coverage.
• Abortion rights: Ballot measures in Idaho, Nevada, Virginia and Missouri brought reproductive rights and access to abortion care into focus.
• Measles and vaccines: The US reported 4,852 confirmed measles cases across 47 jurisdictions as of October 29, 2026. Falling childhood vaccination coverage and changes to federal vaccine recommendations added to concerns.
• Prescription drug prices: Medicare drug price negotiations, Republican drug-pricing initiatives and rising spending on GLP-1 medications featured in the healthcare affordability debate.

Healthcare Candidates Who Won and Lost

More than 100 doctors, nurses and other healthcare professionals entered the 2026 US elections, in what was described as an unprecedented wave of candidates healthcare backgrounds.

Several Democratic candidates with healthcare and public health backgrounds secured major victories. These included:

• Dr. Annie Andrews: A practising paediatrician who defeated Darline Graham in South Carolina, becoming the first woman doctor elected to the US Senate.
• Dr. Amy Acton: A preventive medicine specialist and former director of the Ohio Department of Health who won the Ohio gubernatorial race.
• Dr. Abdul El-Sayed: An epidemiologist and former director of Detroit’s public health department who defeated Mike Rogers in Michigan’s Senate race.
• Xavier Becerra: The former US Health and Human Services (HHS) secretary under the Biden administration who won the California gubernatorial race.

At the same time, several Republican candidates associated with healthcare and the MAHA movement also faced defeats. They included:

• Sen. Roger Marshall: An obstetrician-gynaecologist and founding member of the congressional MAHA Caucus who lost his Senate re-election bid in Kansas to Adam Hamilton.
• Zach Lahn: A prominent MAHA supporter who lost the Iowa gubernatorial race to Democrat Rob Sand.
• Vivek Ramaswamy: A former biotechnology executive who lost the Ohio gubernatorial race to Dr. Amy Acton.
• Rick Jackson: The founder and CEO of Jackson Healthcare who lost the Georgia gubernatorial race to Keisha Lance Bottoms.

Why RFK Jr.’s MAHA Movement Became An Election Issue

The MAHA movement, which promised to tackle chronic diseases and reform America's healthcare system, has faced criticism over Kennedy's approach to vaccines and public health. Changes to federal vaccine recommendations have become contentious amid a measles resurgence threatening the US' measles elimination status.

Pennsylvania reported 1,426 measles cases and five associated deaths as of October 30, 2026, its first measles fatalities in 35 years. The outbreak also triggered a public dispute between Kennedy and Governor Josh Shapiro over the deaths and claims about fetal tissue used in developing the MMR vaccine.

Beyond vaccines, MAHA's push to address ultra-processed foods, food additives and pesticides such as glyphosate has faced criticism over delays and concerns about corporate influence on food policy.

Autism has also emerged as a contentious issue. Trump's and Kennedy's September 2025 announcement on investigating possible autism causes, including a proposed link with acetaminophen use during pregnancy, and the CDC's July 2026 revision questioning the established scientific position on vaccines and autism drew criticism from health experts. Extensive evidence has found no causal link between vaccines and autism.

Looking ahead, Democratic lawmakers could use their control of Congress to scrutinise Kennedy's public health policies, demand scientific evidence behind federal health decisions and push for greater investment in vaccination and disease prevention programmes.

What Could Democratic Control Mean For Vaccine Policy?

Trump's changes to childhood vaccination recommendations could become a focus of congressional scrutiny. In August 2026, he signed an executive order recommending separate MMR shots once individual vaccines become available and separate appointments for childhood vaccinations, where feasible.

Healthcare professionals have warned that additional injections and appointments could complicate vaccination for families and increase the risk of delayed or missed doses.

The administration has also moved away from the universal hepatitis B birth-dose recommendation. Under revised CDC guidance adopted in December 2025, parents of infants born to mothers who test negative can decide with healthcare providers whether to administer the vaccine at birth or begin the series later.

Democrats could hold hearings and investigate changes to CDC vaccine recommendations, the restructuring of its Advisory Committee on Immunization Practices (ACIP), and the removal of vaccine experts from advisory panels. They could also scrutinise staffing and funding changes at federal health agencies.

However, congressional oversight does not automatically allow Democrats to reverse executive decisions or remove Kennedy as HHS secretary. Their influence will depend on their ability to pass legislation, shape federal funding and secure support for changes to the administration's healthcare policies.
