What are the early signs and symptoms of dementia? | The Unforgettable Blog. Worried about problems with your memory? Concerned about the increasing forgetfulness of a partner, parent or family member? Here’s how to spot the first symptoms of dementia While everybody can experience a momentary slip of memory – misplaced keys or a forgotten name – if you or someone you know is repeatedly suffering particular memory problems, it may be worth taking note of the symptoms.
And while it may not be caused by Alzheimer’s disease, vascular dementia or other neurodegenerative problems, it may be worth getting it checked out in case there is an underlying health problem that’s causing the memory loss. Because, while it’s not always easy to differentiate between normal ageing, mild cognitive impairment and dementia, there are some very distinct early symptoms of dementia. These are some dementia symptoms you should look out for: 1. For example, repeatedly forgetting important dates or appointments and having to be reminded of them. 2. 3. 4. 5. 6. 7. 8. 9. 10. Save.
Short Term Memory Loss - What It Is, What Causes It, and How To Prevent It. Understanding Cognitive Aging - Difference between normal aging and dementia. Mild Cognitive Impairment (MCI) | Symptoms & Treatments. Mild cognitive impairment (MCI) causes a slight but noticeable and measurable decline in cognitive abilities, including memory and thinking skills. A person with MCI is at an increased risk of developing Alzheimer's or another dementia. About mild cognitive impairment Mild cognitive impairment causes cognitive changes that are serious enough to be noticed to the person affected and to family members and friends, but do not affect the individual’s ability to carry out everyday activities. Approximately 15% to 20% of people age 65 or older have MCI.
People living with MCI, especially MCI involving memory problems, are more likely to develop Alzheimer’s disease or other dementias than people without MCI. However, MCI does not always lead to dementia. In some individuals, MCI reverts to normal cognition or remains stable. Learn more: Types of Dementia, What Is Alzheimer's? Symptoms Experts classify mild cognitive impairment based on the thinking skills affected: Diagnosis Causes and risks. Dementia | Symptoms, Diagnosis, Causes, Treatments. Dementia is a general term for loss of memory, language, problem-solving and other thinking abilities that are severe enough to interfere with daily life.
Alzheimer's is the most common cause of dementia. Subscribe to E-News to learn how you can help those affected by Alzheimer's. About dementia Dementia is not a single disease; it’s an overall term — like heart disease — that covers a wide range of specific medical conditions, including Alzheimer’s disease. Disorders grouped under the general term “dementia” are caused by abnormal brain changes.
These changes trigger a decline in thinking skills, also known as cognitive abilities, severe enough to impair daily life and independent function. Alzheimer's disease accounts for 60-80% of cases. Dementia is often incorrectly referred to as "senility" or "senile dementia," which reflects the formerly widespread but incorrect belief that serious mental decline is a normal part of aging.

Dementia Types | Symptoms, Diagnosis, Causes, Treatments. Creutzfeldt-Jakob Disease (CJD) | Symptoms & Treatments. Creutzfeldt-Jakob disease (CJD) is the most common human form of a group of rare, fatal brain disorders known as prion diseases. About Creutzfeldt-Jakob disease Prion diseases, such as Creutzfeldt-Jakob disease, occur when prion protein, which is found throughout the body but whose normal function isn't yet known, begins folding into an abnormal three-dimensional shape.
This shape change gradually triggers prion protein in the brain to fold into the same abnormal shape. Through a process scientists don't yet understand, misfolded prion protein destroys brain cells. Resulting damage leads to rapid decline in thinking and reasoning as well as involuntary muscle movements, confusion, difficulty walking and mood changes. CJD is rare, occurring in about one in 1 million people annually worldwide.
Experts generally recognize the following main types of CJD: Sporadic CJD develops spontaneously for no known reason. Chronic wasting disease Learn More From the CDC Symptoms Depression. Diagnosis. Dementia with Lewy Bodies (DLB) | Symptoms & Treatments. Dementia with Lewy bodies (DLB) is a type of progressive dementia that leads to a decline in thinking, reasoning and independent function because of abnormal microscopic deposits that damage brain cells over time. About dementia with Lewy bodies Most experts estimate that dementia with Lewy bodies is the third most common cause of dementia after Alzheimer's disease and vascular dementia, accounting for 10 to 25 percent of cases. The hallmark brain abnormalities linked to DLB are named after Frederich H.
Lewy, M.D., the neurologist who discovered them while working in Dr. Alois Alzheimer's laboratory during the early 1900s. Alpha-synuclein protein, the chief component of Lewy bodies, is found widely in the brain, but its normal function isn't yet known. This overlap in symptoms and other evidence suggest that DLB, Parkinson's disease and Parkinson's disease dementia may be linked to the same underlying abnormalities in how the brain processes the protein alpha-synuclein. Symptoms Diagnosis. Down Syndrome and Alzheimer's | Symptoms & Treatments. As they age, those affected by Down syndrome have a greatly increased risk of developing a type of dementia that's either the same as or very similar to Alzheimer's disease.
About Down syndrome and Alzheimer's Down syndrome is a condition in which a person is born with extra genetic material from chromosome 21, one of the 23 human chromosomes. Most people with Down syndrome have a full extra copy of chromosome 21, and so they have three copies instead of the usual two. In ways that scientists don't yet understand, the extra copies of genes present in Down syndrome cause developmental problems and health issues.
Scientists think that the increased risk of dementia in individuals with Down syndrome may also result from the extra gene. As with all adults, advancing age also increases the chances a person with Down syndrome will develop Alzheimer's disease. One of the many questions researchers hope to answer about Down syndrome is why some people develop dementia symptoms and others don't. Frontotemporal Dementia (FTD) | Symptoms & Treatments. Frontotemporal dementia (FTD) or frontotemporal degenerations refers to a group of disorders caused by progressive nerve cell loss in the brain's frontal lobes (the areas behind your forehead) or its temporal lobes (the regions behind your ears). About frontotemporal dementia The nerve cell damage caused by frontotemporal dementia leads to loss of function in these brain regions, which variably cause deterioration in behavior and personality, language disturbances, or alterations in muscle or motor functions.
There are a number of different diseases that cause frontotemporal degenerations. The two most prominent are 1) a group of brain disorders involving the protein tau and 2) a group of brain disorders involving the protein called TDP43. For reasons that are not yet known, these two groups have a preference for the frontal and temporal lobes that cause dementia. The disorders grouped under FTD fall into three subtypes (discussed below). Types Key differences between FTD and Alzheimer's. Huntington's Disease (HD) | Symptoms & Treatments. Huntington's disease (HD) is a progressive brain disorder caused by a defective gene.
This disease causes changes in the central area of the brain, which affect movement, mood and thinking skills. About Huntington's disease Huntington's disease is a progressive brain disorder caused by a single defective gene on chromosome 4 — one of the 23 human chromosomes that carry a person’s entire genetic code. This defect is "dominant," meaning that anyone who inherits it from a parent with Huntington's will eventually develop the disease. The disorder is named for George Huntington, M.D., the physician who first described it in the late 1800s. The defective gene codes the blueprint for a protein called huntingtin. Symptoms Symptoms of Huntington's disease usually develop between ages 30 and 50, but they can appear as early as age 2 or as late as 80. Huntington's disease brain changes lead to alterations in mood, especially depression, anxiety, and uncharacteristic anger and irritability. Diagnosis. Mixed Dementia | Symptoms & Treatments.
Mixed dementia is a condition in which abnormalities characteristic of more than one type of dementia occur simultaneously. Physicians may also call mixed dementia "dementia – multifactorial. " About mixed dementia In the most common form of mixed dementia, the abnormal protein deposits associated with Alzheimer's disease coexist with blood vessel problems linked to vascular dementia.
Alzheimer's brain changes also often coexist with Lewy bodies. Researchers don't know exactly how many older adults currently diagnosed with a specific type of dementia actually have mixed dementia, but autopsies show that the condition may be significantly more common than previously realized. Autopsy studies play a key role in shedding light on mixed dementia because scientists can't yet measure most dementia-related brain changes in living individuals.

Normal Pressure Hydrocephalus (NPH) | Symptoms & Treatments. Normal pressure hydrocephalus (NPH) is a brain disorder in which excess cerebrospinal fluid (CSF) accumulates in the brain's ventricles, causing thinking and reasoning problems, difficulty walking, and loss of bladder control. About normal pressure hydrocephalus Normal pressure hydrocephalus is a brain disorder in which excess cerebrospinal fluid accumulates in the brain’s ventricles, which are fluid-filled chambers. Normal pressure hydrocephalus is called "normal pressure" because despite the excess fluid, CSF pressure as measured during a spinal tap is often normal. As brain ventricles enlarge with the excess CSF, they can disrupt and damage nearby brain tissue, leading to difficulty walking, problems with thinking and reasoning, and loss of bladder control.
Normal pressure hydrocephalus can sometimes be treated with surgical insertion of a shunt, a long, thin tube that drains excess CSF from the brain to the abdomen. Prevalence Causes and risk factors Symptoms Diagnosis Outcomes Treatment. Posterior Cortical Atrophy (PCA) | Symptoms & Treatments. Posterior cortical atrophy (PCA) refers to gradual and progressive degeneration of the outer layer of the brain (the cortex) in the part of the brain located in the back of the head (posterior).
About posterior cortical atrophy It is not known whether posterior cortical atrophy is a unique disease or a possible variant form of Alzheimer’s disease. In many people with PCA, the affected part of the brain shows amyloid plaques and neurofibrillary tangles, similar to the changes that occur in Alzheimer’s disease but in a different part of the brain. In other people with PCA, however, the brain changes resemble other diseases such as dementia with Lewy bodies or a form of Creutzfeldt-Jakob disease.
Prevalence There is no standard definition of PCA and no established diagnostic criteria, and so it is not possible to know how many people have the condition. Symptoms The symptoms of PCA can vary from one person to the next and can change as the condition progresses. Diagnosis Causes and risks. Parkinson's Disease Dementia | Symptoms & Treatments. Parkinson's disease dementia is a decline in thinking and reasoning that develops in many people living with Parkinson’s at least a year after diagnosis. About Parkinson's disease dementia Parkinson’s disease dementia is a decline in thinking and reasoning that develops in many people living with Parkinson’s at least a year after diagnosis.
The brain changes caused by Parkinson’s disease begin in a region that plays a key role in movement, leading to early symptoms that include tremors and shakiness, muscle stiffness, a shuffling step, stooped posture, difficulty initiating movement and lack of facial expression. As brain changes caused by Parkinson’s gradually spread, they often begin to affect mental functions, including memory and the ability to pay attention, make sound judgments and plan the steps needed to complete a task. Lewy bodies are also found in several other brain disorders, including dementia with Lewy bodies (DLB). Learn more: Lewy Body Dementia and Mixed Dementia Symptoms. Vascular Dementia | Symptoms & Treatments.
Vascular dementia is a decline in thinking skills caused by conditions that block or reduce blood flow to the brain, depriving brain cells of vital oxygen and nutrients. About vascular dementia Inadequate blood flow can damage and eventually kill cells anywhere in the body. The brain has one of the body's richest networks of blood vessels and is especially vulnerable. In vascular dementia, changes in thinking skills sometimes occur suddenly following strokes that block major brain blood vessels. Thinking problems also may begin as mild changes that worsen gradually as a result of multiple minor strokes or other conditions that affect smaller blood vessels, leading to cumulative damage. A growing number of experts prefer the term "vascular cognitive impairment (VCI)" to "vascular dementia" because they feel it better expresses the concept that vascular thinking changes can range from mild to severe.
Other dementias share some common symptoms Learn more: Key Types of Dementia, Mixed Dementia. Korsakoff Syndrome | Symptoms & Treatments. Korsakoff syndrome is a chronic memory disorder caused by severe deficiency of thiamine (vitamin B-1). Korsakoff syndrome is most commonly caused by alcohol misuse, but certain other conditions also can cause the syndrome. About Korsakoff syndrome Thiamine (vitamin B-1) helps brain cells produce energy from sugar.
When levels fall too low, brain cells cannot generate enough energy to function properly. As a result, Korsakoff syndrome may develop. Korsakoff syndrome is most commonly caused by alcohol misuse, but can also be associated with AIDS, chronic infections, poor nutrition and certain other conditions. Alcohol misuse and cognitive decline Alcohol misuse also may lead to brain damage through: The toxic effects of alcohol on brain cells. Korsakoff syndrome is often, but not always, preceded by an episode of Wernicke encephalopathy, which is an acute brain reaction to severe lack of thiamine.

As we and our loved ones age, it’s reasonable to occasionally forget things—we all do it at some points.
However, memory loss, which is defined as “unusual forgetfulness” in both short-term and long-term functions, is not. Memory loss is often automatically associated with Alzheimer’s disease, a medical issue that impacts over five million Americans every year. Memory loss may be a primary symptom of Alzheimer’s, but just because an elderly person is experiencing memory loss, it does not mean he or she has the disease. There are often outside forces and other brain diseases that fuel the degrading of the brain’s cognition. “The indications are that, in the absence of disorders due to trauma or neurological disease, the human brain has the capacity to store almost unlimited amounts of information indefinitely,” one site dedicated to memory loss stated.
But to first understand what types of non-Alzheimer’s causes of memory loss are out there, we must first understand what Alzheimer’s is.
