Dementia and Alzheimer’s are not the same. Dementia is a term used to describe a group of symptoms affecting memory, thinking and social abilities severely enough to interfere with daily functioning. Alzheimer’s disease is the common cause of dementia, accounting for 60-80% of cases. It is a progressive neurodegenerative disorder characterized by the accumulation of abnormal protein deposits in the brain, leading to the gradual loss of neurons and brain tissue.
Alzheimer’s disease typically progresses through several stages. In the early stages, individuals may experience mild memory loss and have difficulty with tasks requiring concentration and organization. As the disease advances, symptoms worsen, leading to significant impairment in memory, language, reasoning and social skills. In the later stages individuals may lose the ability to communicate, recognize loved ones and perform basic activities of daily living.
The brain changes associated with Alzheimer’s disease primarily affect the frontal lobe, temporal lobe, and hippocampus. The frontal lobe is responsible for executive functions such as decision-making and problem solving. The temporal lobe plays a crucial role in memory and language processing, while the hippocampus is essential for forming new memories. As the disease progresses, these brain regions shrink, leading to cognitive decline and functional impairment.
MRI scans can detect structural changes in the brain associated with Alzheimer’s disease, such as shrinkage of the hippocampus and other affected regions. However, MRI alone cannot definitively diagnose Alzheimer’s disease. A comprehensive evaluation including medical history, physical examination, and cognitive assessments is necessary for an accurate diagnosis.
Recent research suggests a potential link between gut health and brain health in dementia. The gut-brain axis, a bi-directional communication system between the gastrointestinal tract and the brain may influence cognitive function and contribute to neurodegenerative processes. Imbalances in gut microbiota composition have been observed in individuals with Alzheimer’s disease. However, further research is needed to fully understand the relationship between gut health and dementia.
Patients with dementia may experience a range of emotional and behavioral changes, including forgetfulness, irritability, agitation, and feeling of abandonment or hopelessness. While some individuals may be aware of their memory problems, others may lack insight into their condition due to cognitive impairment. The progression of dementia varies from person to person with some individuals experiencing a slow decline over several years, while others may deteriorate more rapidly. It is essential for caregivers to monitor the. safety of individuals with dementia and intervene when necessary to prevent accidents or harm. Signs that a person may be unsafe to be alone include wandering, difficulty performing basic tasks, and forgetting to take medications or attend to personal hygiene. Early intervention and support can help improve quality of life for both the individual and the caregivers.
