Definition
Symptoms
- Middle-stage Alzheimer's is typically the longest stage and can last for many years. As the disease progresses, the person with Alzheimer's will require a greater level of care. During the middle stage of Alzheimer’s, the dementia symptoms are more pronounced. the person may confuse words, get frustrated or angry, and act in unexpected ways, such a...
Prognosis
Effects
Diagnosis
- Half or more of the population of persons over the age of 65 experience subjective complaints of cognitive and or functional difficulties. The nature of these subjective complaints is characteristic. Elderly persons with these symptoms believe they can no longer recall names as well as they could 5 or 10 years previously. They also frequently develop the conviction that they can no long…
Preservation
- Various terms have been suggested for this condition, but normal aged forgetfulness is probably the most satisfactory terminology. These symptoms which, by definition, are not notable to intimates or other external observers of the person with normal aged forgetfulness, are generally benign. However, there is some recent evidence that persons with these symptoms do decline a…
Issues
- The dominant mood at this stage is frequently what psychiatrists term a flattening of affect and withdrawal. In other words, the patient often seems less emotionally responsive than previously. This absence of emotional responsivity is probably intimately related to the patients denial of their deficit, which is often also notable at this stage. Although the patient is aware of their shortcomi…
Example
- In the absence of complicating medical pathology, the diagnosis of AD can be made with considerable certainty from the beginning of this stage; Studies indicate that the duration of this stage of mild AD is a mean of approximately two years.
Treatment
- Cognitively, persons at this stage frequently cannot recall such major events and aspects of their current lives as the name of the current president, the weather conditions of the day, or their correct current address. Characteristically, some of these important aspects of current life are recalled, but not others. Also, the information is loosely held, so, for example, the patient may re…
Management
- Remote memory also suffers to the extent that persons may not recall the names of some of the schools which they attended for many years, and from which they graduated. Orientation may be compromised to the extent that the correct year may not be recalled. Calculation deficits are of such magnitude that an educated person has difficulty counting backward from 20 by 2s.
Results
- For example, patients may put their street clothes on over their night clothes. At approximately the same point in the evolution of AD, but generally, just a little later in the temporal sequence, patients lose the ability to bathe independently without assistance (stage 6b). Characteristically, the earliest and most common deficit in bathing is difficulty adjusting the temperature of the bat…
Pathophysiology
- Requires assistance adjusting the temperature of the bath water. At approximately the same time as Alzheimers patients begin to lose the ability to put on their clothing properly without assistance, but generally, just a little bit later in the disease course, patients start to require assistance in handling the mechanics of bathing (Figure 7). Difficulty adjusting the temperature …
Society and culture
- Requires assistance to maintain continence (Figure 9). People with Alzheimers lose the ability to dress, bathe and toilet without assistance, they develop incontinence. Generally, urinary incontinence precedes fecal incontinence. Strategies to prevent episodes of incontinence include taking the patient to the restroom and supervision of toileting.
Clinical significance
- Recall of current events is generally deficient to the extent that the patient cannot name the current national head of state or other, similarly prominent newsworthy figures. Persons at this sixth stage will most often not be able to recall the names of any of the schools which they attended. They may, or may not, recall such basic life events as the names of their parents, their …
