In the United States, it’s estimated that 30 percent of adults and 66 percent of adolescents are regularly sleep-deprived. This isn’t just a minor inconvenience: staying awake can cause serious bodily harm. Claudia Aguirre shows what happens to your body and brain when you skip sleep.
Horizon investigates a new era of Alzheimer's research, which is bringing hope to millions of sufferers across the world. New scanning and gene technology is allowing scientists to identify the disease at its earliest stages, often 15 years before symptoms appear and the brain cells are destroyed. A series of new drugs trials in Colombia, the USA and Europe are showing startling success in reducing beta amyloid, the protein which is a hallmark of the disease. It is also becoming clear that changes in lifestyle can prevent the development of the disease. A new system inside the brain has been discovered which clears amyloid when we are in deep sleep, but allows it to accumulate if we don't sleep well. The programme reveals that for sufferers in the early stages of the disease, brain connections, or synapses, can be strengthened and even replaced by absorbing enough of the right nutrients. A UK-wide trail helps sufferers in the early stages to concentrate on improving everyday tasks, and in the process not only make their lives easier, but helps to reactivate the planning and organisational parts of the brain. In an ageing world, where the biggest risk of developing Alzheimer's is old age, the scientific breakthroughs in Alzheimer's disease are bringing hope where once there was despair.
An ambitious account of the story of human physiology in a feature-length dramatised documentary. Harnessing the magic of the most modern visual effects, we tell the story of the human body—inside and out—as it lives, grows, and dies on this predestined journey we call life. This unique National Geographic docudrama traces the life of a man, Adam, from the Cradle to the Grave, explaining the science behind our highs and lows, the rites of passage we all go through and exploring the inner workings of our bodies and how they change through time. The 90-year-old narrator, Adam, reflects on his life from conception through boyhood, adolescence and beyond, revealing the events that shape him. Along the way we meet the class bully, Adam's first love and the sergeant major preparing him and fellow recruits for Vietnam. With the aid of stunning computer-generated visuals, we go under the skin to reveal how Adam's body responds to major life events, and his story is told in dramatic scenes from the 1950s to the present day.
