Effects Of Aging On The Cardiovascular System
Years of unhealthy habits can really take a toll on your cardiovascular system in later life. Drinking, junk food and high amounts of stress in your younger years can all accumulate and leave you with a weaker heart.
Because our heart does so much for the body, it can take quite a beating during the aging process. Unfortunately, it begins to weaken, which can affect blood pressure and circulation.
Angina: Blood flow to the heart muscle is reduced, resulting in chest pains and even a heart attack.
Abnormal heart rhythms: Heart may speed up, slow down, or have long pauses in between heartbeats.
Anemia: Low iron count can result from malnutrition, blood loss or medications.
Arteriosclerosis: Arteries begin to harden due to deposits of fatty plaque.
Congestive heart failure: Ten times more likely to occur in those over the age of 75.
Coronary artery disease: Results from arteriosclerosis.
High blood pressure: More common in older age. Stress, diet, weight and physical activity can also contribute to high blood pressure.
Aortic stenosis: Narrowing of the aortic valve prevents the proper circulation of blood, causing pooling in the heart.
Support For Families And Alzheimer’s Disease Caregivers
Caring for a person with Alzheimers can have significant physical, emotional, and financial costs. The demands of day-to-day care, changes in family roles, and decisions about placement in a care facility can be difficult. NIA supports efforts to evaluate programs, strategies, approaches, and other research to improve the quality of care and life for those living with dementia and their caregivers.
Becoming well-informed about the disease is one important long-term strategy. Programs that teach families about the various stages of Alzheimers and about ways to deal with difficult behaviors and other caregiving challenges can help.
Good coping skills, a strong support network, and respite care are other things that may help caregivers handle the stress of caring for a loved one with Alzheimers. For example, staying physically active provides physical and emotional benefits.
Some caregivers have found that joining a support group is a critical lifeline. These support groups enable caregivers to find respite, express concerns, share experiences, get tips, and receive emotional comfort. Many organizations sponsor in-person and online support groups, including groups for people with early-stage Alzheimers and their families.

How Does Alzheimer’s Disease Affect The Brain
Scientists continue to unravel the complex brain changes involved in Alzheimers disease. Changes in the brain may begin a decade or more before symptoms appear. During this very early stage of Alzheimers, toxic changes are taking place in the brain, including abnormal buildups of proteins that form amyloid plaques and tau tangles. Previously healthy neurons stop functioning, lose connections with other neurons, and die. Many other complex brain changes are thought to play a role in Alzheimers as well.
The damage initially appears to take place in the hippocampus and the entorhinal cortex, which are parts of the brain that are essential in forming memories. As more neurons die, additional parts of the brain are affected and begin to shrink. By the final stage of Alzheimers, damage is widespread and brain tissue has shrunk significantly.
Study Shows Link Between Alzheimers And Heart Disease
Recently, researchers discovered that Alzheimers is caused by amyloid beta proteins building up in the spaces between brain cells. While this causes noticeable symptoms in the brain first, this same protein plaque can build up around the heart.
This was discovered in a study that examined 22 patients with Alzheimers and 35 patients without, all of whom were 78 or 79 years old. The goal was to analyze the stiffness present in the hearts left ventricle the thickest chamber of the heart responsible for transporting blood throughout the body.
During the study, published in the Journal of the American College of Cardiology, researchers discovered that those with Alzheimers had a thicker left ventricle than those without Alzheimers. This thickness was caused by the same plaque protein buildup that was building in the Alzheimers patients brains. The thickness can lead to various cardiovascular issues if and when the left ventricle becomes too thick to successfully pump blood through the body. As a result, this puts Alzheimers patients at a higher risk of heart attack and stroke.

Pathology Of Alzheimers Disease
Gross Anatomy of Alzheimers Brain. Lateral view of an Alzheimers brain can show widening of sulcal spaces and narrowing of gyri compared to a normal brain. This may be more readily observed in coronal sections as indicated by the arrowheads, and this atrophy is often accompanied by enlargement of the frontal and temporal horns of the lateral ventricles as highlighted by the arrows. Additionally, loss of pigmented neurons in the locus coeruleus is commonly observed in the pontine tegmentum as shown with the open circle. None of these features is exclusive to Alzheimers disease
The definitive diagnosis of AD requires microscopic examination of multiple brain regions employing staining methods that can detect Alzheimer type neuropathologic change , with diagnosis based upon the morphology and density of lesions and their topographic distribution. Several of the brain regions that are vulnerable to Alzheimer type pathologic change are also vulnerable to other disease processes, such as -synucleinopathy and TDP-43 proteinopathy. Mixed pathology is common. Indeed in the Mayo Clinic Brain Bank from 2007 to 2016 , the majority of AD cases had coexisting non-Alzheimer pathologies, and comorbidities increased in frequency with age. Furthermore, when the original clinical diagnoses were examined for cases with pure AD pathology, it is clear that a number of clinical syndromes can masquerade as Alzheimers disease.

What Does This Project Involve
The researchers on this project are hoping to understand more about the role of the immune system in Alzheimer’s disease to find out if there is a way to target the microglia more effectively with treatments. The team have previously used cutting-edge imaging techniques in fruit flies that have shown that immune cells will travel to areas of the brain where the amyloid protein is present. It is thought that the microglia travel to the amyloid in order to remove it from the brain, but if they become overactive they may end up damaging the brain cell in the process. The researchers will therefore use this imaging technique to understand how the cells travel during the disease process and what the relationship is between the microglia and the amyloid protein. They will then unpick the genetic and molecular aspects that control this behaviour.
Vascular Contributions To Alzheimers Disease
People with dementia seldom have only Alzheimers-related changes in their brains. Any number of vascular issuesproblems that affect blood vessels, such as beta-amyloid deposits in brain arteries, atherosclerosis , and mini-strokesmay also be at play.
Vascular problems may lead to reduced blood flow and oxygen to the brain, as well as a breakdown of the blood-brain barrier, which usually protects the brain from harmful agents while allowing in glucose and other necessary factors. In a person with Alzheimers, a faulty blood-brain barrier prevents glucose from reaching the brain and prevents the clearing away of toxic beta-amyloid and tau proteins. This results in inflammation, which adds to vascular problems in the brain. Because it appears that Alzheimers is both a cause and consequence of vascular problems in the brain, researchers are seeking interventions to disrupt this complicated and destructive cycle.

How Is Alzheimers Disease Treated
Alzheimers is complex, and it is therefore unlikely that any one drug or other intervention will successfully treat it in all people living with the disease.
Scientists are exploring many avenues to delay or prevent the disease as well as to treat its symptoms. In ongoing clinical trials, scientists are developing and testing several possible interventions. Under study are drug therapies aimed at a variety of disease interventions, as well as nondrug approaches such as physical activity, diet, cognitive training, and combinations of these. Just as we have many treatments for heart disease and cancer, we will likely need many options for treating Alzheimers. Precision medicine getting the right treatment to the right person at the right time will likely play a major role.
Current approaches to treating Alzheimers focus on helping people maintain mental function, treating the underlying disease process, and managing behavioral symptoms.

What This Means For Patients And Families
This study will be integral in helping those suffering with Alzheimers disease. Because amyloid beta deposits can develop in the heart, it is important that the families and healthcare providers of people with Alzheimers be on the lookout for signs of heart disease.
There is still no cure for Alzheimers. However, there have been many advancements in treatment for the disease that have allowed people with Alzheimers to live longer than previously expected when first diagnosed. This is great news, but it does mean that there is a higher chance they may develop heart problems along the way due to their disease. Thanks to this new research, however, patients suffering from Alzheimers can now better avoid potential cardiovascular issues in the future by being aware of the high risk and monitoring their health closely.
Causes Of Alzheimer’s Disease
The brain is made up of billions of nerve cells that connect to each other. In Alzheimers disease, connections between these cells are lost. This is because proteins build up and form abnormal structures called plaques and tangles. Eventually nerve cells die and brain tissue is lost.
The brain also contains important chemicals that help to send signals between cells. People with Alzheimers have less of some of these chemical messengers in their brain, so the signals are not passed on as well. There are some drug treatments for Alzheimers disease that can help boost the levels of some chemical messengers in the brain. This can help with some of the symptoms.
Alzheimers is a progressive disease. This means that gradually, over time, more parts of the brain are damaged. As this happens, more symptoms develop, and they also get worse.More than 520,000 people in the UK have dementia caused by Alzheimers disease and this figure is set to rise.
