Dementia occurs when there is a decline in cognitive function. There are several reasons why this might happen, and the cause will dictate the type of dementia a person is diagnosed with. Patients with dementia often experience issues with memory, mood, hallucinations, communication and some motor skills. At Dementech Neurosciences, we have an in-house team of dementia specialists who can work with dementia patients and caregivers to mitigate the side effects of the condition.

Types of Dementia

Dementia is an umbrella term that covers several types of illnesses. The type of dementia a person has will influence the cognitive symptoms they experience. Several other conditions can cause or mimic the symptoms of dementia, and a small percentage of dementias are reversible.
Two common examples are dementia caused by vitamin B12 deficiency or thyroid dysfunction. Dementia could also be a symptom of pernicious anaemia. Below, we explore various types of dementia.

Alzheimer’s Disease

Alzheimer’s disease is the most common form of dementia. It’s thought that two proteins are responsible for Alzheimer’s: amyloid and tau. Abnormal deposits of amyloid clump up around brain cells, whilst deposits of tau make brain cells become ‘tangled’. Neurotransmitters become affected which means brain signals aren’t set properly, resulting in cognitive issues. Where the protein deposits are in the brain will affect the symptoms the patient has.

Frontotemporal Dementia

Frontotemporal dementia is one of the only types of dementia that is somewhat more prevalent in younger people, with most patients being between 45 and 65. Frontotemporal dementia happens when tau protein clumps together on the front and temporal lobes, causing nerve damage and killing brain cells. This type of dementia can run in families.

Lewy Body Dementia

Lewy body dementia is caused by cumps of Lewy bodies (a type of protein), which deposit in the brain and eventually kill brain cells.

Parkinsonian Dementia

Parkinsonian dementia is similar to Lewy body dementia, but the cognitive impairment develops after a year of Parkinson’s disease symptoms become known. If the cognitive impairment develops before the loss of motor skills, it’s likely Lewy body dementia.

Dementia Symptoms

There are a number of symptoms that you might experience if you have dementia. Typically speaking, symptoms start slowly and get worse over time. Some people find their symptoms develop gradually and they live with the disease for many years, but other people may find that their symptoms rapidly get worse. The symptoms a dementia patient experiences may vary depending on what type of dementia they have and which part of the brain is affected. Common symptoms may include:

  • Problems concentrating 
  • Hallucinations 
  • Memory loss 
  • Issues with judgement and reasoning 
  • Mood changes 
  • Sleep disruption 
  • Change in appetite

People experience dementia differently depending on what area of their brain is being affected. Generally, the outlook for patients with dementia is a gradual decline resulting in a loss of independence eventually. Most people survive their diagnosis for 6-12 years, but some can live longer.

Causes of Dementia & Rapidly Progressive Dementia

It is difficult to determine exactly what causes dementia, and even more challenging when it comes to Rapidly Progressive Dementias (RPDs). RPDs are quite rare, and refer to dementias that progress over the course of weeks / months rather than years. RPDs can be challenging to diagnose as there is less time to conduct essential tests that help to build a full picture of the condition. Below we explore some potential causes of dementia.

Pernicious Anaemia

This is custom heading elementPernicious anaemia is thought to be one of the common causes of dementia. This is a type of anaemia brought on by a vitamin B12 deficiency and can cause cognitive issues if left untreated.

In older people, the first symptoms of pernicious anaemia are often confusion, slowness, irritability, and apathy. An overproduction of thyroid hormones (hyperthyroidism), as well as an underproduction (hypothyroidism), can cause dementia-like symptoms.

Wernicke-Korsakoff Syndrome

The Wernicke-Korsakoff syndrome is an irreversible state of confusion and amnesia in alcoholics, resulting from thiamine deficiency due to long-term malnutrition. Consuming excessive amounts of alcohol for a decade or more can also cause impaired thinking that resembles Alzheimer’s disease (AD).

In dementia due to alcoholism, memory, orientation, and attention deteriorate, although verbal skills are not always severely affected. In this type of dementia, abstinence may partly restore mental functioning.

Normal-Pressure Hydrocephalus

Normal-pressure hydrocephalus (“water on the brain”) is an excess of cerebrospinal fluid around the brain, which can also cause dementia. This condition can result from head trauma, brain haemorrhage, or meningitis (inflammation of the membrane covering the brain), but most cases occur spontaneously without an obvious preceding illness.

In addition to developing dementia, people with this condition lose bladder control and walk in a slow, hesitant manner, as if their feet are stuck to the floor.

Brain Tumours and Hematomas

Brain tumours can interfere with cognitive functioning and cause personality changes. Depending on the location of the tumour, they can also trigger other symptoms, such as headaches, seizures, or vomiting.

Hematomas are blood clots caused by bruising. When they are located in the subdural area, between the brain surface and the thin membrane that covers it, they can cause symptoms that mimic AD.

The type of dementia a person has will influence the cognitive symptoms they experience. Several other conditions can cause or mimic the symptoms of dementia, so having symptoms of dementia doesn’t necessarily mean you have the disease.

Get a Dementia Diagnosis

Getting the right dementia diagnosis is vitally important. An accurate diagnosis will provide a clear picture of the options you have available in terms of treatment, which could allow you to live independently for longer.

After this, you will be referred for an MRI scan and blood tests to make sure there’s no other conditions that could be causing your symptoms. Following this, you will receive a diagnosis and a treatment plan will be actioned. This can all be completed within a week.

At Dementech Neurosciences, our team of doctors can provide a rapid and accurate diagnosis of the various forms of dementia and devise a bespoke treatment plan. Creating a plan early on in your dementia diagnosis can help you feel more in control of your condition.

To accurately diagnose dementia, we will require you to come in for a consultation where we will assess you and try to gauge what your symptoms are. We will also take into account your medical history.

Choosing a Private Neurologist

Dementia is a time-critical disease. The earlier it’s caught and treated, the more positive the outcome is for the patient. Whilst there’s no cure, symptoms can be managed for many years.

No Waiting Lists

By choosing a private neurologist, you won’t have to wait weeks to see a specialist or to undergo tests. We provide same-day consultations and rapid diagnostic testing so early intervention can begin as soon as possible.

Clinical Trials

We offer suitable patients the chance to take part in clinical trials of new pharmaceutical drugs that aren’t yet available to the public. Whilst there’s a chance the medications may not work, they could manage the symptoms of dementia in conjunction with the other therapies and treatments offered at Dementech.

Private Dementia Care Fees

As a private clinic, we do charge a fee for access to our services which is payable before appointments. If you would like more information on our fees, please get in touch with us and we’ll be happy to discuss this with you.
