Why is it important to have a caregiver for Alzheimer's?
Most patients with Alzheimer's disease have a primary caregiver — often a family member — who is crucial to ensuring appropriate care for your patient with dementia. Caregivers often strive to meet all of the health and personal needs of the person with dementia , but they often neglect their own.
What are the key elements of a dementia management strategy?
Key elements of a strategy to maximize dementia outcomes include regular monitoring of patient's health and cognition, education and support to patients and their families, initiation of pharmacologic and nonpharmacologic treatments as appropriate, and evaluation of patient/family motivation to volunteer for a clinical trial.
How do caregivers help with dementia?
Caregivers often strive to meet all of the health and personal needs of the person with dementia, but they often neglect their own. Many caregivers report high levels of stress, which can contribute to illness. Nearly 40 percent suffer from depression. Physicians and other health care professionals can help by looking for signs of caregiver burnout, treating medical problems and referring them to support services, such as the Alzheimer's Association's 24/7 Helpline (800.272.3900). Our Alzheimer's caregiving information offers guidance on how to maintain physical and mental health in the midst of caregiving, as well as advice on how to manage their loved one's daily care, enhance their daily life, and respond to behaviors.

What is the best test for Alzheimer's?
For example, for decades, one simple cognitive test has been a mainstay in helping to diagnose Alzheimer’s disease and other impairments: the clock-drawing test. In this test, a neuropsychologist or other examiner asks the patient to draw a clock showing a specific time (often 10:11). Healthy patients can do this easily, but those with dementia struggle, drawing clocks with irregular shapes, with uneven number spacing and with hands pointing to the wrong time.

What is the future of AD drug development?
What does the future hold for AD drug development? Perhaps as Lon Schneider has observed, success in AD drug development awaits a dramatically effective therapy able to provide a convincing demonstration of its worth despite problems with the methods available to support increased successes in drug developments (Personal Communication). This ultimately compelling effect size for outcomes occurred with sulfa drugs and early antibiotics. It seems unfortunate if AD drug development must wait on similar circumstances to recur. One alternative is the further documentation and quantification of risks from biases, recruiting of lower cost but effective interventions against bias effects, justifications for advances short of disease modifications and their implicit need for definite supports in addition to clinical status. Each of these has the potential to provide a step towards the identification of a critical path through the slough of biases and lead investigators towards needed certainty for validity realized at reasonable costs.
How many AD trials have failed?
Less attention is paid to a more fundamental issue potentially able to explain some of the 200 failed AD trials and perhaps critical to the success of future AD clinical research and advances in design and methods. In analyses of various AD and other neuropsychiatric drug developments, various authors found numerous methodological weaknesses capable of biasing these clinical trials and drug developments and thus invalidating conclusions to be reached about the drugs being tested [6–9]. Given the number of failures of AD drug developments it may be the case that adherence to current AD drug development norms or standards of practice does not adequately protect validity [1]. All too prevalent risks shown to compromise the validity of AD and other clinical trials include dosing, biases, ineptitude and deception, protocol violations, measurement errors, and so forth [6–9] and can be found to interfere with validity in other’s and our analyses [5–16]. A recent analysis of documentation for one clinical trial revealed that some of the trial conditions were statistically significantly predictors for outcomes, grounds to declare that trial invalid as a test of the drug [10]. Yet, this trial had contributed to the abandonment of the drug and to general acceptance that the drug had failed in development for AD. Based on these and other findings and evidence from cognitive science methodological deficiencies in AD drug developments could too easily go undetected and invalidate an unknown number of AD drug research efforts and future efforts to assess the effectiveness of new strategies, such as the current turn towards prevention of AD [11].
How many subjects are in a phase II trial?
Given the usual size of 400 or more subjects in current Phase II and III clinical trials countermeasures may become economical if they reduce the overall size of these studies [7]. Clearly whatever the outcomes from any one redesigned clinical trial, one test will not justify any conclusions about how AD drug developers might best proceed to insure progress towards success finding efficacy. On the one hand, aware of the costs of methodological innovations that other’s and our earlier research has supported, we have become concerned that higher per-subject costs may well make potentially sounder and thus more likely successful AD drug developments impractical to implement without access to less costly quality controls. On the other hand, the scientific progress in biomarker, monitoring, subject status rating, and other clinical trial methods may offer routes to overcome problems of error compromises that are leading AD drug candidates to be abandoned. The lack of adequate financial resources or know-how to integrate these innovations may hold back evaluation and adoption of methodological innovations needed to support progress towards successful AD drug developments. AD clinical neuroscience may find appropriate increased emphases on funding for methodological research and innovation with priority given to economical preemptive interventions able to guard against invalidation of clinical trials. Our earlier studies of error and bias effects in AD drug development, more focused on the risks themselves, appear to have underestimated the costs of solutions to these risks to validity.
Why have AD drug candidates failed?
Current opinion generally holds that AD drug candidates have failed because they address pathology that is already too advanced [2]. Consequently recent expert advice has centered on detecting and treating persons who are at risk of AD rather than persons diagnosable with AD [2]. This strategy and the methodological advances it will spawn have not yet been fully tested for effectiveness because of the difficulties associated with implementation: the problems of distinguishing non-AD, yet destined to develop AD, subjects from simply cognitively impaired but clinically stable subjects; the availability of outcome variables appropriate to document progressions into disease modifications or failures of at-risk subjects to proceed towards AD; the slow development of this ND disease requiring double-blinded, placebo or otherwise controlled clinical trials of 18 months or longer duration; and similar factors [3]. These same problems complicate the evaluation of design and method proposals meant to overcome the difficulties associated with current approaches to AD drug developments [4,5].
