DEMENTIA Alzheimers disease There are many is the most common cause of a progressive causes of dementia dementia. symptoms.
  • DEMENTIAPer the Diagnostic Statistical Manual IV- Revised (DSM-IV-TR), dementias share a common symptompresentation but are differentiated based on etiology, or cause.The essential feature of any dementia is the development of multiple cognitive deficitsthat include:• memory impairmentand at least one of the following cognitive disturbances:• aphasia (language disturbance),• apraxia (impaired ability to carry out motor activities despite intact motor function),• agnosia (failure to recognize or identify objects despite intact sensory function), and• executive dysfunction (difficulty in planning, organizing, sequencing, abstracting).The deficits must also be sufficiently severe and must represent a decline from a previouslyhigher level of functioning.The diagnosis of dementia may be accompanied by subtypes and specifiers such as• Early (before the age of 65) or Late Onset (after 65)• With Behavioral Disturbance (e.g., wandering, striking out during care);• With Delirium (if delirium is superimposed on dementia);• With Delusions (if delusions are most prominent feature);• With Depressed Mood (if depressed mood is most prominent feature); and• Uncomplicated (if none of the aforementioned predominates the clinical presentation).

But the end stages of subcortical dementia result in the same breakdown of brain function as in the cortical dementias.
  • FUNCTIONS OF THE CORTEX
  • CORTICAL DEMENTIAS• Alzheimer’s disease• Vascular dementia• Frontotemporal dementia• Creutzfeldt-Jacob disease
  • ALZHEIMER’S DISEASE brain disorder, most common form of dementia ASSOCIATED RISK FACTORS: • Age • Family history Affects 5% of people at age • Down syndrome 65 • Incidence higher in women • Alcohol use • Atherosclerosis Affects 50% of people age • Blood pressure 85+ • Cholesterol • Depression Late-onset • Diabetes (type 2) (age 65+) is most common, slowest- progressing Average course of DAT: 6-20 years
  • AD (cont.) – 10 WARNING SIGNS Memory loss that disrupts daily Challenges in Changes in functioning planning or mood and solving personality problems Difficulty Withdrawal completing from work or familiar tasks at social activities home, at work or WARNING at leisure SIGNS Decreased or Confusion with poor judgment time or place Misplacing Trouble things and understanding losing the visual images ability to retrace New problems and spatial steps with words in relationships speaking or writing
  • Plaques TanglesAcethylcholine Deficiency
  • AD – STAGESIt is important to keep in mind that stages are general guides, and symptoms vary greatly. Noteveryone will experience the same symptoms or progress at the same rate. This seven-stageframework is based on a system developed by Barry Reisberg, M.D., clinical director of the NewYork University School of Medicines Silberstein Aging and Dementia Research Center.Stage 1: No impairment (normal function)The person does not experience any memory problems. An interview with a medicalprofessional does not show any evidence of symptoms of dementia.Stage 2: Very mild cognitive decline (may be normal age-related changes or earliestsigns of Alzheimers disease)The person may feel as if he or she is having memory lapses — forgetting familiar words or thelocation of everyday objects. But no symptoms of dementia can be detected during a medicalexamination or by friends, family or co-workers.
  • AD – STAGESStage 3: Mild cognitive decline (early-stage Alzheimers can be diagnosed in some,but not all, individuals with these symptoms)Friends, family or co-workers begin to notice difficulties. During a detailed medical interview,doctors may be able to detect problems in memory or concentration. Common stage 3difficulties include:• Noticeable problems coming up with the right word or name• Trouble remembering names when introduced to new people• Having noticeably greater difficulty performing tasks in social or work settings• Forgetting material that one has just read• Losing or misplacing a valuable object• Increasing trouble with planning or organizing
  • AD – STAGESStage 4: Moderate cognitive decline (Mild or early-stage Alzheimers disease)A careful medical interview should be able to detect clear-cut problems in several areas:• Forgetfulness of recent events• Impaired ability to perform challenging mental arithmetic• Greater difficulty performing complex tasks, such as planning dinner for guests, paying bills or managing finances• Forgetfulness about ones own personal history• Becoming moody or withdrawn, especially in socially or mentally challenging situationsStage 5: Moderately severe cognitive decline (Moderate or mid-stage AD)Gaps in memory and thinking are noticeable, and individuals begin to need help with day-to-day activities. At this stage, those with Alzheimers may:• Be unable to recall their own address or telephone number or the high school or college from which they graduated• Become confused about where they are or what day it is• Have trouble with less challenging mental arithmetic; such as counting backward from 40 by subtracting 4s or from 20 by 2s• Need help choosing proper clothing for the season or the occasion• Still remember significant details about themselves and their family• Still require no assistance with eating or using the toilet
  • AD – STAGESStage 6: Severe cognitive decline (Moderately severe or mid-stage AD)Memory continues to worsen, personality changes may take place and individuals needextensive help with daily activities. At this stage, individuals may:• Lose awareness of recent experiences as well as of their surroundings• Remember their own name but have difficulty with their personal historyRemember:It is difficult to place a person with Alzheimers in a specific stage as stages may overlap.• Distinguish familiar and unfamiliar faces but have trouble remembering the name of a spouse or caregiver• Need help dressing properly and may, without supervision, make mistakes such as putting pajamas over daytime clothes or shoes on the wrong feet• Experience major changes in sleep patterns — sleeping during the day and becoming restless at night• Need help handling details of toileting (for example, flushing the toilet, wiping or disposing of tissue properly)• Have increasingly frequent trouble controlling their bladder or bowels• Experience major personality and behavioral changes, including suspiciousness and delusions (such as believing that their caregiver is an impostor)or compulsive, repetitive behavior like hand-wringing or tissue shredding• Tend to wander or become lost
  • AD – STAGESStage 7: Very severe cognitive decline (Severe or late-stage Alzheimers disease)In the final stage of this disease, individuals lose the ability to respond to their environment, tocarry on a conversation and, eventually, to control movement. They may still say words orphrases.At this stage, individuals need help with much of their daily personal care, includingeating or using the toilet. They may also lose the ability to smile, to sit withoutsupport and to hold their heads up. Reflexes become abnormal. Muscles grow rigid.Swallowing impaired.
  • AD - TREATMENT• No treatment is available to slow or stop the deterioration of brain cells in Alzheimers disease.• The US Food and Drug Administration has approved five drugs that temporarily slow worsening of symptoms for about 6 - 12 months.• These are effective for only about half of the individuals who take them.• Inconclusive research: o Vitamin E o Anti-inflammatory drugs o Estrogen o Vaccine o Diet www.alz.org/research/overview.asp

  • PREPARING FOR A DOCTOR’S VISITIf someone is experiencing symptoms, or is concerned about dementia it iscritical to GET EVALUATED. The confusion or memory loss may be treatable. Why? If you have AD, you want to be involved in your own planning for the future while you are still able. Current treatment is most effective when started early.
