Early Dementia Warning Signs: Mood Changes Could Be An Indicator
Experts caution that a sustained “shift in disposition” lasting up to two years may signal the onset of dementia. This initial indication can manifest as “subtle” and become more pronounced over time. Spotting these early changes is crucial for timely intervention and care.
Understanding Dementia and its Initial Symptoms
Dementia is recognized as a syndrome, encompassing a cluster of related symptoms, associated with the progressive deterioration of brain function. Predominantly affecting individuals over 65, dementia often initially presents with difficulties concerning memory. Recognizing these early symptoms is vital for prompt diagnosis and management.
Subtle Signs of Dementia: Beyond Memory Loss
While memory impairment is a well-known symptom, there are less obvious indicators that might suggest the presence of dementia. The Alzheimer’s Society highlights that “In the nascent phases of dementia, an individual’s symptoms are frequently relatively inconspicuous and not consistently straightforward to detect.”
The organization further elaborates, “Typical initial-stage symptoms encompass challenges with recollection, cognitive processing speed, communication, or understanding.” They estimate, “As a general benchmark, the initial stage of dementia typically extends for approximately two years.”
Mood and Emotional Changes: A Key Early Indicator
The charity has identified several prevalent “early” symptoms that can affect an individual’s daily life. Among these, alterations in mood or emotion are particularly noteworthy as potential warning signs of dementia. Recognizing these shifts is important for early detection.
It further clarified, “Individuals may exhibit heightened anxiety, fearfulness, or sadness, thus increasing their vulnerability to depression. Increased irritability is also common – potentially stemming from frustration with diminished capabilities – or heightened sensitivity. A person might also become more isolated, experience diminished self-assurance, and lose enthusiasm for pastimes or social interactions.”
Depression and Dementia: A Complex Relationship
The precise origins of depression in dementia patients remain unclear, but research suggests a multifaceted interplay of factors.
The Alzheimer’s Society notes, “For numerous individuals, the difficulties inherent in living with dementia can give rise to profound sentiments of sadness or despair. Furthermore, the diseases that precipitate dementia can inflict damage to areas of the brain governing emotions and conduct.”
Factors Contributing to Depression in Dementia
Additional elements that can contribute to depression include:
- Prior experiences of traumatic or distressing events
- Co-existing health conditions or disabilities – notably heart conditions, respiratory problems, persistent pain, or hormonal imbalances
- Adverse effects of medications – including certain sleep aids, steroids, beta-blockers, and medications for Parkinson’s disease
- Insufficient engaging activities, social isolation, or inadequate social support networks
- Lack of sufficient restorative sleep
- Bereavement – which can heighten vulnerability to depression, although grief is typically not categorized as a form of depression
- Stress related to concerns such as finances, interpersonal relationships, or future prospects
- Excessive alcohol consumption
Increased Risk of Depression in Those with Prior History
The charity emphasizes that an individual with dementia is “considerably more susceptible” to developing depression if they have experienced depression previously – especially in cases of multiple prior episodes.
According to the organization, manifestations of apathy, depression, and anxiety are likely to persist into the intermediate stage of dementia, highlighting the ongoing emotional challenges associated with the condition.
Other Initial Signs of Dementia
Beyond mood changes, the charity lists other early indicators of dementia to be vigilant for:
- Memory impairments
- Difficulties with logical reasoning and planning
- Challenges in language and communication
- Spatial disorientation – becoming easily lost
- Visual-perceptual difficulties.
Seeking Medical Advice
If you or someone you know is displaying potential dementia symptoms, it is advisable to consult a physician. Early diagnosis and intervention are essential for managing dementia and providing appropriate support.
