Does brain atrophy always mean dementia?
A mild degree of brain atrophy is not always a concern. Substantial brain atrophy can be associated with major neurological diseases, such as a large stroke or progressive dementia. In some instances, it isn't clear whether cerebral atrophy caused the medical condition or vice versa.
Is mild brain atrophy serious?
Mild cases of brain atrophy may have little effect on daily functioning. However, brain atrophy can sometimes lead to symptoms such as seizures, aphasia, and dementia. Severe damage can be life threatening. A person should see a doctor if they experience any symptoms of brain atrophy.

However, this atrophy is accelerated in people with mild cognitive impairment and even faster in those who ultimately progress from mild cognitive impairment to Alzheimer's disease.
Is brain atrophy Alzheimer's?
In Alzheimer's disease, as neurons are injured and die throughout the brain, connections between networks of neurons may break down, and many brain regions begin to shrink. By the final stages of Alzheimer's, this process—called brain atrophy—is widespread, causing significant loss of brain volume.

Which part of the brain is most affected by generalized cerebral atrophy?
In Alzheimer’s disease, the most common cause of dementia, the hippocampus and the cortex are two areas especially affected.
What are the types of cerebral atrophy?
Refers to cerebral atrophy that is restricted to a localized area of the brain, often causing damage to the affected area. Atrophy of a particular region of the brain can lead to motor, sensory, or cognitive dysfunction, depending on the region of the brain affected.

This is believed to be the result of the number of brain cells naturally declining with age. Some areas of the brain are affected by this generalized form of brain atrophy more than others, like the hippocampus, which is involved in memory. However, a person’s cognitive function is often not affected.
What is generalized atrophy?
Generalized atrophy. Also known as complete or total cerebral atrophy, this type of cerebral atrophy is characterized by shrinkage of total brain size.

Researchers from the Boston University School of Medicine found that people who were in poor physical fitness during their 40s had significantly lower brain volumes by the time they reach age 60. 3
How does blood pressure affect the brain?
Fluctuations in blood pressure can damage small vessels in the brain that are vulnerable to such changes. Such vascular damage in the brain can then contribute to structural changes and cognitive losses. The researchers were interested in looking at how these dramatic blood pressure changes could contribute to later structural changes in the brain.

Which lobe of the brain is most atrophy in AD?
In the present study, more atrophy was observed in AD than in healthy controls in almost all ROIs, including prefrontal cortex. However, temporal lobe atrophy was the most prominent in AD, while healthy aging was characterized by comparable rates of atrophy in the temporal lobe and the frontal cortex.
What is the right panel of Alzheimer's disease?
The right panel shows 1 year atrophy in AD patients. The areas of change in the healthy elderly are overlapping with areas most strongly affected in Alzheimer's disease, e.g., temporal lobe cortex. However, areas that are not especially affected in AD, e.g., prefrontal cortex, also undergo large changes in healthy aging.
Does brain atrophy accelerate with age?
The present results show that widespread changes in brain structure can be found in healthy elderly over only 1 year, and that atrophy accelerates with advanced age. Some of the atrophy occurred in areas vulnerable to AD and some in areas less characteristic of the disease in early stages.
What separates losses due to normal aging from those caused by disease?
In the low-risk participants, Fjell and colleagues saw the greatest atrophy in the default-mode network (DMN), a series of interconnected brain regions that become more active when the mind is at rest and unfocused. This network is susceptible to Alzheimer's pathology (see ARF related news story ). While DMN losses also occurred in patients with MCI or AD, a distinct pattern emerged in the low-risk population. They exhibited greater atrophy in the prefrontal cortex, especially the orbitofrontal region, compared to patients with mild cognitive impairment or Alzheimer's disease.
What are the areas of the brain affected by dementia?
Most areas of the brain were affected, with the hippocampus and amygdala losing about 1 percent and cortical regions about 0.5 percent. "There are a lot of changes in the brain that cannot be ascribed to incipient dementia," said Fjell. "These changes could be due to either normal aging or other pathologies that we are not able to detect.".
How long does it take for the cortex to shrink?
In 2009, researchers led by Anders Fjell at the University of Oslo, Norway, found that the cortex, known to shrink in patients with mild cognitive impairment and Alzheimer's disease, also diminished in older healthy people within as little as one year.
Where is volume measured in the brain?
The most useful region in which to track volume changes may not be in brain tissue per se, but rather in the culvert-like structures within the brain that contain cerebrospinal fluid. In JAMA Neurology, researchers led by Deniz Erten-Lyons of Oregon Health and Science University, Portland, report that swelling in the ventricles associates strongly with Alzheimer's pathology and with dementia diagnosis confirmed on autopsy.
Does hippocampal atrophy cause AD?
The researchers also found no correlation between AD path ology and hippocampal atrophy, which is widely reported in AD (see, e.g., Barnes et al., 2009 ). This was surprising, said Erten-Lyons. She suggested that hippocampal loss may have occurred earlier in the course of the disease. "Potentially, we didn't start imaging our subjects early enough to see changes in the hippocampus," she said. However, the authors did find that hippocampal shrinkage associated with cortical amyloid angiopathy (CAA), or deposits of amyloid in blood vessels. The investigators argued that the hippocampus is more susceptible to reduced blood flow that occurs in CAA.
Is low hippocampal volume a surrogate marker for Alzheimer's?
Because brain atrophy in Alzheimer's patients precedes clinical symptoms, researchers have proposed using it as a surrogate marker for pathology in clinical trials and longitudinal studies. For example, in October 2011, the European Medicines Agency deemed low hippocampal volume an acceptable selection marker for clinical trials of people in the early, predementia, stages of Alzheimer’s disease (see ARF related news story ).
Does AD affect cognitive impairment?
Further complicating the story, Erten-Lyons and colleagues found that when they controlled for AD pathology, volume changes still associated with dementia and mild cognitive impairment. "This suggests that there may be other factors not measured in this study that could be contributing to brain atrophy in those with cognitive impairment," wrote the authors. Erten-Lyons suggested that genetics, lifestyle, and nutrition are worth considering. “The relationship between pathology and brain atrophy is not simple and linear," said Erten-Lyons. Neither is the distinction between aging and disease, said Jagust. "It is complicated because we don’t know where disease begins and where it ends," he said.—Susan Young
Why does the brain shrink as we age?
It is not so much that neurons die, but that their terminals and synaptic junctions shrivel. A known cause is the over-secretion of cortisol by stress, but perhaps there are also other age-related causes.
How much cortical volume does memory lose?
Some in the average group lost as much as 3.4 percent of their cortical volume per year. If that were to continue over the next 10 years, they would suffer a devastating loss of over 30 percent of their cortical volume.
What is considered a super ager?
Certain people are "super-agers," defined as adults over 80 with a memory at least as good as normal middle-aged adults. A usually reliable index for the decline in memory ability is the degree of brain shrinkage, specifically cortical volume.
Is shrinkage a good thing?
It is possible that some shrinkage is a good thing, reflecting perhaps a pruning of neural circuitry as the brain learns and develops more efficiency. Pruning is a conspicuous phenomenon in the brains of the fetus and infants as maturation progresses.
Do super agers score higher on cognitive and memory tests?
Super-agers scored higher on cognitive and memory tests than the average group at both the beginning and end of the study period.
Can super agers have brain atrophy?
It is possible that something about the lifestyle of super-agers protected them from brain atrophy. It is not convenient to know how much cortical volume the elderly had in their youth. But the second option has been tested in a study that compared the rate of cortical aging in 36 adults averaging 83 years of age.
Is age discrimination defensible?
Obviously too much pruning can leave neural circuitry with insufficient resources. These results also emphasize that age discrimination is not defensible. Each elderly person's mental competence has to be judged on its own merits, not on a negative stereotype of the elderly. References.
