What is dementia?

What are some of the signs and symptoms of dementia?

The symptoms of dementia vary depending on which parts of the brain are affected and the underlying cause. Regardless of specific symtpoms, dementia can be debilitating and distressing. Here are some common signs of dementia:Some common signs and symptoms of dementia include: 

• Memory loss: A person with dementia might start to show signs of forgetfulness and lose their memory of recent events, names, where they live, and more. They may also start to misplace items around the house, become disoriented, get lost in familiar places or lose track of time easily.
• Communication issues: Dementia can affect communication and cause a person to struggle with finding the right words and expressing themselves effectively.
• Impaired decision making: Judgement and planning may be affected, making it more difficult to make effective decisions, assess risk, organise things and solve problems.
• Mood and personality changes: Dementia can cause changes in a person’s mood, typically before other symptoms appear. For example, increasing irritability or anger, or making them more anxious or depressed.
• Lack of interest: Those with dementia may start to lose interest in activities they once found enjoyable, such as hobbies or social gatherings.
• Struggles with daily tasks: Everyday tasks like getting washed and dressed or cooking dinner can become much more difficult for someone with dementia.

Symptoms of dementia often worsen over time, and many individuals will eventually need assistance with daily activities. If you’re concerned about rapidly advancing dementia, check out our article: What To Know About Rapid Onset Dementia

How is dementia diagnosed? 

Diagnosing dementia is a process that requires discussion with the individual themselves and their family in order to fully understand the scope of symptoms and how far they have progressed. The National Institute for Health and Care Excellence says diagnosis of dementia typically involves steps such as:

• Undertaking an initial assessment to understand the person’s medical history by speaking to them and people who know them well, such as family or close friends.
• Assessing the person’s current level of cognition and function, compared to whatever is considered to be their base level. The aim is to determine whether or not there has been a significant decline in cognition since the onset of symptoms. 
• Asking questions about the impact symptoms have on daily activities, such as eating, getting dressed, continence, taking medications, managing personal finances, and so on. 
• Asking questions about safety in the home and elsewhere.
• Discussing any cognitive, behavioural or psychological changes.
• Looking at the risk factors for dementia, such as family history, alcohol or drug use, medication history, and more. 
• Assessing for any coordination abnormalities, sensory issues, motor symptoms, visual or auditory problems, cardiovascular signs, or other causes of symptoms.
• Arranging relevant blood tests to rule out other possible causes of symptoms.

If you believe you or a loved one may have symptoms of dementia, the process of being diagnosed may seem frightening, but it is important to address symptoms as soon as possible in order to find out if dementia is the true cause, or if something else could be the problem. In any case, the earlier you seek medical help for symptoms of dementia, the more chance there is to potentially slow the progression of the disease and put help in place for you ahead of other symptoms developing. 

How is dementia treated and managed?

There is no cure for dementia, so treatment is focused on managing the symptoms and ensuring those with the disease remain as healthy as possible for as long as possible, with the best quality of life possible. Dementia can be managed with:

• Medications: For some types of dementia, there are medications available that can help to alleviate symptoms and keep the brain working well for longer. 
• Therapy: Certain therapies can help people with dementia maintain their functional abilities. 
• Support: Support from family, close friends and caregivers is so important for those with dementia so they continue to feel safe and surrounded by people they trust when other things in life feel uncertain. 
• Lifestyle modifications: Maintaining a healthy diet and getting regular exercise and movement has been shown in studies to help slow cognitive decline. Creating a structured routine can help those with dementia to feel more confident, and they should also be encouraged to continue taking part in hobbies and social gatherings if desired. 
• Environmental modifications: Ensuring the home environment is safe and optimised for a person with dementia is important to help them continue their normal daily routine as much as possible and maintain independence for longer. 

While treatment will not stop dementia from progressing, having a multidisciplinary Care Plan in place can help to ensure those living with dementia continue to feel safe and supported, and can maintain their independence. You may find our article on the dementia care plan useful: Building A Care Plan For A Dementia Patient At HomeCan anything be done to lower the risk of dementia? Lifestyle adaptations can help to lower the risk of developing dementia later in life, so if this is something you are worried about, you may wish to adopt some of the below healthy practices:

• Regular physical exercise or movement – This should be a mix of aerobic and strength-training if possible 
• Maintain a healthy diet – Try to include lots of fruits, vegetables, and omega-3 fatty acids in your meals
• Take care of your heart – Cardiovascular risk factors like hypertension and diabetes can contribute to cognitive health too, so look after your heart to look after your brain 
• Mental stimulation – Stay mentally stimulated with activities like reading, puzzles and social interactions
• Avoid excessive alcohol consumption – Evidence suggests that excessive alcohol consumption increases risk of dementia, so managing your alcohol intake is recommended
• Quit smoking – Smoking is associated with an increased risk of dementia, so quitting is the best way to reduce your likelihood of developing the disease later in life  
• Getting enough sleep – Studies have suggested that not getting enough sleep can increase your risk of dementia later in life, so prioritising this is important 
• Manage stress levels – Chronic stress has been associated with an increased risk of cognitive impairment and Alzheimer’s disease, so managing your stress levels is important
