Amnestic disorder vs dementia8/24/2023 But those improvements don't clearly carry over to day-to-day life. The AAN also notes that cognitive training may improve thinking skills, although the evidence is weak.Ĭognitive training involves computer- or video-based exercises that push you to sharpen your response times and attention. The new MCI treatment guidelines recommend exercising at least twice a week. Exercising can offer mental and social stimulation while improving blood flow to the brain, possibly even prompting the release of molecules that repair brain cells and create connections between them. There are no pills to slow the worsening of memory problems.īut the AAN did find encouraging evidence linking exercise with better memory in people with MCI. When MCI can't be reversed, treatment is challenging. In those cases, addressing the underlying cause can dramatically improve cognition. Salinas says MCI can often be reversed if a general health condition (such as sleep deprivation) is causing the decline. But I've seen patients stay in the MCI stage for many years, even when we presume it was a neurodegenerative disease," Dr. "If it's Alzheimer's disease, it may take about two to five years. Salinas says the progression is much more likely if a neurodegenerative disease such as Alzheimer's is causing the MCI.īut how long it takes for MCI to progress to dementia is anyone's guess. 27, 2017, by Neurology, also note that MCI cases progress to full-blown dementia about 15% of the time among people 65 or older. The guidelines, which were published online Dec. The number climbs to more than 37% by age 85. New MCI treatment guidelines from the American Academy of Neurology (AAN), based on the latest evidence, note that globally more than 6% of people in their 60s have MCI. It may show up as problems with language (you lose your train of thought during a conversation), attention (you have a hard time accomplishing tasks like bill paying), or spatial sense (you can't find your way around a familiar place). Non-amnestic MCI involves changes in other brain activities regardless of whether you have memory loss. In both, symptoms are not severe, although they can be upsetting and disruptive.Īmnestic MCI is memory-specific and is marked by signs like forgetting conversations and misplacing items. Symptoms can include forgetfulness, confusion, and the new inability to solve routine problems. Medical conditions - such as Alzheimer's disease, Parkinson's disease, traumatic brain injury, and strokes - are common causes of dementia. It often stems from disease or treatments for disease, includingĭegenerative brain disease, such as Alzheimer's disease (in which case, MCI is often a precursor to dementia)Īn underlying health problem, such as sleep deprivation, depression, or anxiety.ĭementia is a condition of persistent impairment in brain activities - like thinking or speaking - that is severe enough to interfere with daily life. MCI is not dementia (see "What is dementia?"), but it's not normal thinking, either. Joel Salinas, a neurologist at Harvard-affiliated Massachusetts General Hospital. "It depends on the underlying cause," says Dr. But the progression from MCI to dementia is not automatic. Will I get dementia? That common question takes on urgency if you have mild cognitive impairment (MCI), a slight but noticeable change in memory and thinking skills. The shift from this condition to dementia is not necessarily inevitable.
