The reports of its prevalence in various populations range from approximately 10% to as high as 88%, although it is generally thought that the prevalence of everyday memory problems lie within the range of 25% to 50%. It has been suggested that <strong>SCD may be an indication of cognitive decline at a very early stage of a neurodegenerative disease (i.e. preclinical stage of Alzheimer&#8217;s disease) that is undetectable by standard testing instruments<\/strong>. SCD may represent the first symptomatic manifestation of Alzheimer&#8217;s disease in individuals with unimpaired performance on cognitive tests.<\/p>\n<div id=\"text\">\n<p>The McNair and Kahn Scale or Cognitive Difficulties Scale was employed to define and characterize cognitive complaints in the GuidAge study, involving a population of more than 2800 individuals aged 70 years or older having voluntarily complained of memory problems to their general practitioner (GPs). It contains items that are related to <strong>difficulties in attention, concentration, orientation, memory, praxis, domestic activities and errands, facial recognition, task efficiency, and name finding<\/strong>.<\/p>\n<p>The results of the GuidAge study suggest that the assessment of cognitive complaint voluntarily reported to primary-care physicians, by the McNair and Kahn scale can predict a decline in cognitive performance, as 5 items out of 20 were statistically significant.<\/p>\n<p><strong>These 5 items are:<\/strong><\/p>\n<ul>\n<li>item 1, &#8220;I hardly remember usual phone numbers&#8221;,<\/li>\n<li>item 5, &#8220;I forget appointment, dates, where I store things&#8221;,<\/li>\n<li>item 6, &#8220;I forget to call people back when they called me&#8221;,<\/li>\n<li>item 10, &#8220;I forget the day of the week&#8221;,<\/li>\n<li>item 13, &#8220;I need to have people repeat instructions several times.&#8221;<\/li>\n<\/ul>\n<p>Thanks to this short scale GPs, in clinical practice, can identify which patients with memory complaints should be referred to a memory center to assess cognitive functions.<\/p>\n<\/div>\n<\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the IOS Press press release: A memory complaint, also called Subjective Cognitive Decline (SCD), is a subjective disorder that appears to be relatively common, especially in elderly persons.
