Patients with dementia generally do not consult physicians just after the onset of the disease; they tend to live with it before seeking diagnosis and treatment, finds a new study. The findings of this study are going to be discussed in 33rd European Association of Urology conference.
The study also suggests that home-based, patient-centered care may improve early screening and detection of dementia.
Alzheimer's disease is the most common form of dementia and may contribute to 60-70 percent of cases.
"The findings indicate that people are living with dementia for significant periods of time before seeking diagnosis and treatment," said Timothy Thoits, MD, lead author, and neurology division chief, Spectrum Health Medical Group. "The earlier the diagnosis, the earlier treatment can begin and the earlier the benefit to the patient and his or her family and caregivers."
The Spectrum Health research showed no link between cohabitation and earlier diagnosis of the disease. Previous research on the relationship between cohabitation and dementia severity at the time of diagnosis is controversial, with some research showing earlier diagnoses for patients who live alone, and another study showing earlier diagnoses for patients who live with a son or daughter than for patients living alone or with a spouse.
Thoits and his team of researchers reviewed the initial diagnostic patient evaluations, which included a neurological examination, Montreal Cognitive Assessment and a battery of neuropsychological testing. They determined dementia stage and severity by correlating it with the number of lifestyle changes recommended at the time of diagnosis-a novel study method that has not previously been used.
These lifestyle changes include medication assistance, financial assistance, driving restrictions and institutional care. At the time of diagnosis, providers had recommended lifestyle changes in 75.8 percent of patients with dementia.
The study concludes that "an increase in home-based, patient-centered medical care, regardless of the patient's living status, may be one way to improve recognition of cognitive deficits and increase the frequency of important and necessary early cognitive evaluations."
The World Health Organization (WHO) defines home-based care as "any form of assistance provided to a sick person referred to as the patient directly in the home by family, friends, and members of the local community, cooperating with the advice and support from the trained health workers."
According to the WHO:
- Dementia is a syndrome in which there is deterioration in memory, thinking, behavior and the ability to perform everyday activities.
- Although dementia mainly affects older people, it is not a normal part of aging.
- Worldwide, around 50 million people have dementia, and there are nearly 10 million new cases every year.
- Alzheimer's disease is the most common form of dementia and may contribute to 60-70 percent of cases.
- Dementia is one of the major causes of disability and dependency among older people worldwide. It has a physical, psychological, social and economic impact, not only on people with dementia but also on their careers, families, and society at large.
