MCI has gradually worsening cognitive symptoms and occurs before significant memory loss in Alzheimer’s dementia.

Alzheimer’s disease (AD) and mild cognitive impairment (MCI) are two of the most common forms of dementia, or conditions that cause memory loss and other intellectual impairments. AD and MCI may be classified based on the degree of impairment. Mild cognitive impairment is a transitional stage between normal thinking and dementia. In this publication, we will compare and contrast the symptoms, diagnostic criteria, treatment, causes, incidence rates, outcomes, and risk factors of AD and MCI.

A cognitive disorder whereby a person’s memory becomes impaired, but their mental abilities remain at the same level. To have MCI, a person’s memory must be worse than usual for his or her age and education; however, it does not interfere with daily tasks. A patient must also demonstrate another cognitive impairment in order to be diagnosed with MCI. These symptoms include language skills, learning, ability to pay attention, and reasoning. Diagnosing MCI is more complicated than identifying the symptoms of this condition because they are not as easily noticed as other symptoms of Alzheimer’s dementia.

Both Alzheimer’s and MCI refer to changes in mental outlook or functioning that signify the beginning of a decline in memory and thinking skills. Symptoms of MCI tend to be less severe than those of Alzheimer’s, and the memory loss does not interfere with day-to-day activities.

Dementia is a general term for a brain disease that causes problems with memory, thinking, and behavior. Dementia can develop from Alzheimer’s disease or from moderate to severe head injury, brain infections, brain tumors, stroke, or Parkinson’s disease.

Plus, many of the usual symptoms of MCI, dementia and Alzheimer’s disease can be caused by other diseases, including a blood clot or tumor in the brain (not Alzheimer’s, but cancer or a vascular disease). So, to determine if you are or may be suffering from Alzheimer’s disease or another form of dementia, your health care provider will examine memory decline as one potential symptom within the context of other factors to help make a diagnosis. In addition to testing for cognitive decline, your doctor will do a thorough assessment of all other possible causes for memory loss before making a diagnosis.

Alzheimer’s disease is a progressively degenerative neurological condition that affects a person’s ability to carry out daily activities. The Mayo Clinic defines Alzheimer’s as “a brain disorder that gradually destroys memory and a person’s ability to think, reason, make decisions and solve problems.” People suffering from Alzheimer’s usually care for their health, but still face difficulties carrying out daily activities independently. This can be an extremely stressful and upsetting situation for family members and friends who are caring for the individual.

A patient’s cognitive abilities diminish as a result of this chronic disease that is the sixth leading cause of death in the United States.
