Five common habits that age your brain revealed by doctor
Speaking on Lorraine on Thursday (10 July), Dr Amir Khan explained that multitasking, which he described as "like having too many apps open in your head," raises cortisol — a stress hormone — and studies have shown that it decreases gray matter in your brain which is responsible for focus and emotion, Dr Amir explained.
He went on to describe how chronic sleep deprivation, doom scrolling, skipping meals, and reduced social contact can also have a big impact.
"If you're not seeing people, our brains are designed to gossip.
"If you're not doing that, that can lead to social isolation, which has been linked to dementia, and one researcher linked social isolation to the equivalent of having 15 cigarettes a day."

EXCLUSIVE SNP MSP breaks ranks to call for NHS Fife boss Carol Potter and her board to RESIGN over gender storm
A Nationalist MSP has broken party ranks to urge NHS Fife bosses to quit over their handling of a transgender legal battle. Michelle Thomson last night hit out at the health board as it was revealed the dispute with nurse Sandie Peggie had so far cost taxpayers £220,500. The Falkirk East MSP is the first serving SNP politician to condemn NHS Fife's handling of the landmark tribunal relating to single-sex spaces. She accused the board – headed by chief executive Carol Potter, who earns at least £147,700 a year – of a seemingly 'breathtaking disregard for their duties of good governance and candour'. And the MSP raised concerns about the 'direct, and indirect cost to the public purse... at a time when the wider NHS is struggling'. Heaping pressure on Health Secretary Neil Gray to step in, Ms Thomson said she would be 'disappointed' if he continued to insist he had confidence in the board. Her intervention follows revelations last week that the health board had spent hundreds of thousands of pounds defending itself and trans medic Dr Beth Upton against a claim brought by Mrs Peggie. The 50-year-old A&E nurse has taken her case to an employment tribunal after being suspended from her job. NHS Fife chiefs took action against her after she challenged the presence of Dr Upton, born a biological male, in the female changing rooms at Kirkcaldy's Victoria Hospital. The huge costs associated with the ongoing tribunal were revealed on Wednesday following a months-long transparency battle between MailOnline and the health board. However, those close to the case said the true legal bill could climb to around £1 million once the tribunal, which continues this week, concludes. That would likely include extra internal legal costs and fees for outside counsel for NHS Fife, which is using an expensive English-based KC to defend their position, as well as the claimant Sandie Peggie's legal fees, which can later be requested from the health board. The case started before April's Supreme Court ruling clarified that the definition of a woman under the Equality Act 2010 is based on biological sex, meaning trans women have no automatic right to access female-only spaces. Last night Ms Thomson said: 'It cannot just be me who has considered what on earth is going on in the board of NHS Fife. 'The Supreme Court judgement was extremely clear, and so to then proceed with the remainder of the Peggie hearing when it can only result in abject failure for them seems to have breathtaking disregard for their duties of good governance and candour.' She added: 'The cost to the public purse will be significant at a time when the wider NHS is struggling. 'It's clear to me that all of the board must consider their position'. She added she would be 'extremely surprised and disappointed' if My Gray continued to claim he had confidence in NHS Fife and its leadership. Last week NHS Fife conceded that as of May 31, 2025, a total of £220,465.93 had been spent on legal costs relating to the tribunal. It was noted that the sum could pay for nine nursing assistant starting salaries of £23,362 or around 40 hip replacements. The Scottish Government last night said the Health Secretary continues to have confidence in NHS Fife and its leadership.

Militant union bosses urge doctors not to tell their hospitals if they are striking – sparking fears for patient safety
MILITANT union bosses are telling doctors they do NOT have to alert their NHS trust if they are planning to strike - sparking fears for patient safety. It will make it harder for trusts to plan cover to keep hospitals running. 7 7 7 Resident doctors, formerly known as junior, are walking out for five days at the end of July as they demand a 29 per cent pay rise. Dr Ross Nieuwoudt, co-leader of the British Medical Association's resident doctors committee, accused trusts of trying to 'deceive' docs into revealing strike plans. He blasted a cancer trust which told staff it was a mandatory requirement to report action to their team each day of the strike. 'This is absolutely unacceptable,' he wrote on X. 'You do NOT have a legal responsibility to disclose whether you are striking. 'Trusts will attempt to deceive or compel you to tell them. If they do, let a BMA rep know.' 7 Legally union members do not have to tell their employer if they are going to strike. But sources said most resident doctors told their trusts whether they intended to strike - which helped hospitals to secure enough staff to keep running. One insider said: 'It shows they don't give a damn about patient safety.' Daniel Elkeles, chief executive of NHS Providers, which represents hospital bosses, said: 'Given the huge disruption and impact on patient care caused by strikes it is good practice for staff to make their intentions known. 'That way hospitals plan with the best information so that fewer patients have their care cancelled and that reduces the amount of harm that the strikes will cause.' Shadow health secretary Edward Argar said: 'This is potentially a serious threat to patient safety. 'It's shocking that we don't even know how many doctors will walk out, and hospitals are being left in the dark. 'That kind of chaos puts patients and lives at risk. These strikes are irresponsible, unnecessary and wrong.' 7 One of Britain's most loved TV doctors Lord Robert Winston resigned from the union this week slamming their "highly dangerous" strikes. The 84-year-old professor, who pioneered IVF treatments in the UK, quit after more than 60 years as a member of the BMA. The last round of doctors' strikes cost the NHS £1.7 billion and led to 1.5 million cancellations. Health Secretary Wes Streeting told the Commons the average first-year doctor earns £43,275 - 'significantly more than the average full-time worker in this country'. 7 7 Some resident doctors on a 40-hour week, including a full 'on-call' rota, can earn more than £100,000 a year, according to analysis by the Telegraph. A BMA spokesperson said: 'Doctors intending to take strike action are under no obligation to inform their employers of those intentions. But with nine out of 10 of our members who voted in the ballot, voting in support of strike action, it is reasonable they will participate in the strikes if they are due to be working and trusts should plan accordingly.'
