Understanding The Progression Of Frontal Lobe Dementia And Its Effects On The Brain
Frontal lobe dementia is generally considered to be a type of dementia that primarily affects the brain's frontal and temporal lobes. This type of dementia may also be referred to as frontal-subcortical dementia, frontotemporal dementia (FTD), or frontal lobe disorders. As the disease progresses, it may have an immense impact on a person's daily life. Frontal lobe dementia can negatively impact executive function, behavior, personality, memory, and communication. Understanding FTD’s progression and effects on the brain can help individuals with the disease navigate these changes. While there may not be a cure for dementia at this time, FTD symptoms can be managed with a variety of interventions, including online therapy.
The importance of the frontal and temporal lobes in brain function
Frontotemporal dementia (FTD) primarily affects the frontal and temporal lobes of the brain—regions that are responsible for several vital functions. The frontal lobe is generally the largest part of the brain. It normally plays a role in various functions in the brain, including those that control movement, behavior, language abilities, emotions, and decision-making. It’s sometimes also called the executive area of the brain because it is typically responsible for higher-level functions, such as organizing tasks, planning, and problem-solving.
The temporal lobe is associated with encoding our memory and processing what we hear. It provides the ability to understand the meaning of words and helps you recognize familiar objects and faces.
Effects of frontal lobe dementia on the brain
The brain's frontal lobe is often critical for many vital functions, including movement control, emotion management, decision-making, and cognitive processes. When nerve cells in the temporal and frontal lobe are lost due to frontal lobe dementia, it can significantly impact an individual's ability to perform everyday tasks and engage in meaningful activities. Thought to be caused by deposits of proteins called tau, frontotemporal lobar degeneration can cause unusual behaviors, trouble communicating, and other challenges. Some of the specific effects of frontal lobe dementia on the brain can include the following:
Impairment of executive functions: As frontotemporal degeneration progresses, individuals with frontal lobe dementia may experience a decline in their ability to pay attention, plan, organize, and problem-solve, potentially making it difficult to carry out complex tasks.
Changes in behavior and personality: Individuals with frontal lobe dementia may experience mood, personality, and behavior changes. They may become apathetic, disinhibited, exhibit changes in their social behavior, and display compulsive behaviors (e.g., compulsive eating).
Memory difficulties: Short-term memory may be affected, potentially making it challenging for individuals to recall recent events or retain new information.
Communication difficulties: Frontal lobe dementia can affect communication, potentially causing individuals to have trouble with speech, writing, and comprehension. They may also experience difficulty finding the right words to express themselves.
Overall, the effects of frontal lobe dementia on the brain can have a significant impact on an individual's quality of life and ability to perform everyday tasks.
Types of frontal lobe dementia
Frontal lobe dementia occurs in various neurodegenerative diseases. The symptoms of these neurological disorders are different from the symptoms of Alzheimer’s. For example, a prominent symptom of Alzheimer’s is early memory loss, while certain behavioral symptoms can indicate a person may have FTD.
Knowing the specific kind of frontal lobe dementia can help you better manage FTD symptoms and work with your healthcare providers to outline a course of treatment. Below are a few common types.
Behavioral variant frontotemporal dementia (bvFTD)
Behavioral variant FTD (bvFTD) is the most common frontotemporal dementia. It differs from other types of dementia (e.g., Alzheimer’s disease) in that patients often retain their memory but exhibit unusual behaviors such as acting impulsively and saying inappropriate things, struggling with planning and sequencing, and becoming disinterested in their family or previously enjoyed hobbies.
Primary progressive aphasia
Affecting the parts of the brain responsible for language skills, primary progressive aphasia (PPA) is a less common form of FTD that encompasses three variant disorders—progressive non-fluent aphasia, semantic variant primary progressive aphasia, and logopenic variant primary progressive aphasia. This syndrome is characterized by language symptoms and impacts a person’s ability to communicate. Deficits in language ability may include trouble speaking, understanding what others are saying, reading, and writing. Other symptoms include the inability to recognize common objects and familiar faces.
Movement disorders such as amyotrophic lateral sclerosis
Conditions including corticobasal syndrome, progressive supranuclear palsy, frontotemporal dementia with Parkinson’s, and frontotemporal dementia with amyotrophic lateral sclerosis may cause movement symptoms, such as body stiffness, along with changes in thinking abilities.
Diagnosing frontal lobe dementia
Frontal lobe dementia has no known risk factors aside from genetic factors. Experts have linked certain genetic variants with different forms of frontotemporal dementia. For that reason, genetic tests have been developed to diagnose these disorders. A diagnosis of frontal lobe dementia may also be made after a comprehensive evaluation by a healthcare professional, which may include a physical exam, neuropsychological testing, and laboratory tests. However, only genetic tests or a brain autopsy can be used to diagnose frontal lobe dementia with 100% accuracy.
Imaging studies, such as magnetic resonance imaging or a CT scan, may be performed to track disease progression. Other brain scans, like positron emission tracer (PET) and single-photon emission computed tomography (SPECT) scans, can also be employed. Additionally, the healthcare professional may gather information from family and caregivers about the individual's symptoms, personal medical history, family medical history, and changes in behavior and cognition. This information can help to provide a complete picture of the individual's condition in order to diagnose frontotemporal dementia.
Diagnosis of frontal lobe dementia may not always be straightforward, as its symptoms can be similar to other neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and Huntington's, as well as a mental health condition such as a mood disorder.
Medications may help people with frontotemporal dementia to manage specific symptoms, such as agitation or sleep disturbances, and various therapies can address cognitive and behavioral changes. Once a diagnosis of frontal lobe dementia has been made, the healthcare professional may work with the individual and their family to develop a treatment plan that addresses their specific needs and goals.
In some cases, further testing, such as a lumbar puncture or a brain biopsy, may be necessary to determine the underlying cause of frontal lobe dementia. These tests may determine if frontal lobe dementia was caused by a specific disease or condition, such as Creutzfeldt-Jakob disease. Pick's disease is another possibility, as some patients with frontotemporal lobe dementia have Pick bodies in their brain cells, which contain abnormal protein amounts or types.
Overall, diagnosing frontal lobe dementia can be a complex process that usually involves a comprehensive evaluation by a healthcare professional and a thorough review of the individual's symptoms, medical history, and behavior. With the right support and treatment, it can be possible to manage the symptoms of frontal lobe dementia and improve the quality of life for people with an FTD diagnosis.
Frontal lobe dementia treatment options
There is likely no cure for frontal lobe dementia, but treatment options may be available to manage symptoms and improve quality of life. These can include:
Medications to manage behavioral symptoms, such as agitation or depression
Occupational, physical, and speech therapy
Supportive care and counseling for both the individual with dementia and their caregiver(s)
Participation in community-based programs and activities that can provide social interaction and stimulation
Coping with frontal lobe dementia
Living with the symptoms of frontotemporal dementia can be a challenging experience for individuals with dementia and their loved ones. Try to keep in mind that there is usually support available for people with FTD. Here are some tips for coping with frontal lobe dementia:
Learn as much as you can about the condition, including its progression and treatment options
Consider if you are interested in participating in any available clinical trials
Seek support from family, friends, and professional organizations and support groups, as well as treatment options like physical and occupational therapy
Create a support network that includes healthcare providers, family, and friends
Establish routines and maintain a structured schedule to help with memory and decision-making
Encourage individuals with dementia to engage in activities they enjoy, such as hobbies or exercise, to help boost their mood and motivation
Talk to family members about what support will look like during the course of the disease progression
Manage caregiver stress and take time for self-care to prevent burnout
Secure social security disability benefits, as FTD automatically qualifies you for approval
Benefits of online therapy
Through online therapy, individuals with frontal lobe dementia can work on managing their dementia symptoms, such as behavioral changes and memory loss, and improving their overall quality of life. For caregivers, therapy can provide a supportive and safe environment to discuss their challenges and experiences and develop coping strategies. Additionally, online therapy may offer educational resources and guidance for individuals and families navigating the complexities of frontal lobe dementia. Plus, it can be easy for those with dementia and their caregivers to reach out, as they can attend sessions from the comfort of their homes.
Effectiveness of online therapy
Studies have found that cognitive behavioral therapy (CBT) can be helpful for symptoms like memory loss and executive functioning deficits. This type of therapy is generally as effective online as it is in person, offering those with dementia and their caregivers more than one valid option for getting professional help.
Takeaway
How does frontal lobe dementia affect communication?
There are two broad types of frontotemporal dementia (FTD): behavioral variant frontotemporal dementia and primary progressive aphasia. The behavioral variant is primarily associated with the frontal lobes and is characterized by changes in behavior and personality. In contrast, progressive aphasia is associated mainly with the temporal lobes and is characterized by problems using language.
One of the many functions of the temporal lobe is to store the meanings of words, recognize objects, and name them. Difficulties with language and communication are among the first noticeable changes in someone with the aphasic version of FTD. The person may lose their vocabulary over time or forget the function of familiar objects.
How long can a person live with frontal lobe dementia?
It is difficult to predict how long a person will live after being diagnosed with frontotemporal dementia. The disease affects both the frontal and temporal lobes of the brain, which can cause many different symptoms that vary from person to person. Evidence suggests that some people live more than ten years after being diagnosed, while others live less than two.
The factors contributing to how long a person is likely to live include the specific variant of the dementia. If it is the behavioral variant, frontotemporal dementia likely reduces longevity more than if it is the aphasic variant, which is characterized by trouble using language. It is likely that a person diagnosed at a younger age will live longer than those diagnosed in old age.
How does frontotemporal dementia affect quality of life?
Frontotemporal disorders impact quality of life significantly, but the exact effects depend on the dementia variant and how long the disease has progressed. The behavioral variant is primarily associated with changes in personality and behavior. Nerve degradation is most pronounced in brain areas that control conduct, judgment, and foresight. The aphasic variant is characterized by trouble using language and communicating. A person might forget what words mean or what familiar objects are used for.
FTDs are progressive, and every who is diagnosed will eventually experience a significant impact on quality of life. In the early stages, a person may be able to accommodate the disorder and find solutions for specific problems. Quality of life can also be increased if the person has assistance and is encouraged to remain independent for as long as possible.
Some motor disorders are also part of the frontotemporal degeneration spectrum. Amyotrophic lateral sclerosis (Lou Gehrig’s disease), corticobasal syndrome, progressive supranuclear palsy, and other types of motor neuron disease can all cause problems with motor control and muscle weakness, with or without behavior or language problems. Motor disorders may significantly affect a person’s ability to function independently, lowering their quality of life.
What to expect with frontal lobe dementia?
The early signs of frontotemporal dementia depend on the specific variant. The behavioral subtype is primarily characterized by strange or unusual behavior and shifts in personality. In contrast, the aphasic subtype is primarily characterized by problems using language and communicating. Changes usually start subtly, but dementia is progressive. Eventually, symptoms will increase to a level that prevents a person from living independently.
Common changes in the behavioral subtype include a loss of self-control, apathy, trouble empathizing, unusual eating, or difficulty completing complex tasks. Common changes in the aphasic variant include trouble getting words and sentences out (nonfluent dementia) or a loss of understanding of what words mean (semantic dementia).
There is no treatment for frontotemporal dementia, although speech therapy may be helpful in the early stages of the aphasic subtype. Supportive treatment can help improve quality of life and extend the amount of time a person can live independently, but eventually, the dementia will spread beyond the frontal or temporal lobes and affect the rest of the brain.
How do you communicate with someone who has frontal lobe damage?
Communicating with someone who has frontal lobe damage is sometimes challenging, but there are a few basic steps that can make the process easier:
Speak slowly and clearly using simple sentences.
Wait for responses and repeat yourself if necessary.
Ask questions if you don’t understand something.
Use gestures, photographs, or other visual aids to help the person understand what you are trying to say.
Follow guidance from the person’s speech therapist, if applicable.
How does memory loss affect the use of language in a person with dementia?
Memory loss resulting from dementia can impair language usage. Those with a family history of Alzheimer’s disease may be aware of the profound communication problems that can occur when a person struggles to recall the meaning and proper use of words. In the early stages, language usage is likely slowed, but word knowledge is intact. The person also likely remembers the names of common objects and what they are used for.
As dementia progresses, the person will likely lose the ability to remember the definitions of certain words and may struggle to identify once-familiar objects. To them, it may feel as though they know the word they are trying to communicate but cannot vocalize it, which may cause frustration when interacting with others.
Eventually, the person will lose nearly all language utility as memory loss prevents them from utilizing their vocabulary. As with other brain disorders, the exact course of memory loss due to dementia is difficult to predict. The person’s medical team, which likely includes specialists like a speech-language pathologist and neuropsychologist, can likely make recommendations based on the unique course of their dementia.
How does frontotemporal dementia affect mobility?
Two variants are typically used to describe frontotemporal dementia: behavioral and primary aphasia. The behavioral subtype affects behavior and personality, and the aphasic subtype affects language usage and communication. However, recent evidence suggests that there is a significant overlap between frontotemporal dementia and some motor control disorders. Common symptoms include muscle rigidity, flailing movements, difficulty swallowing, and difficulty coordinating motion.
How does frontotemporal dementia affect information processing?
Frontotemporal dementia’s behavior variant is associated with several cognitive deficits related to information processing. Those with the behavioral variant may find it challenging to plan, organize and make decisions. They may reach illogical conclusions or struggle to solve problems.
The aphasic variant is associated with trouble processing language information. A person may need help remembering what words mean, identifying common objects, or remembering how to use ordinary things. The language challenges can make communication difficult, as well as affect how the person receives and processes information from the world around them.
How do you manage frontotemporal dementia?
There is no cure for frontotemporal dementia and no known way of slowing its progression. Supportive care can be used to help manage symptoms as they occur and worsen over time, which can significantly improve quality of life and overall well-being. Below are some common strategies for supporting someone with frontotemporal dementia:
Behavior and personality changes can be managed by remembering that the illness is causing the change, not the person. Do not argue or reason with the affected person; they cannot control their behavior and likely do not understand that it may upset others.
Language problems can be addressed by speaking slowly and clearly, waiting longer than usual for responses, and asking clarifying questions. It may also be helpful to use gestures, drawings, photographs, or other visual aids to help the person make relevant connections.
Movement problems are generally managed through medications, physical therapy, and occupational therapy. The movement problems associated with frontotemporal dementia are similar to other motor control disorders and generally require medical management by a professional who specializes in such disorders.
What are the personality changes in frontotemporal dementia?
Personality changes are common in the behavioral variant of frontotemporal dementia. People with that type of dementia often experience problems with executive function and self-control. They may become disinhibited and act in ways that are not socially appropriate, such as making rude comments, staring at others, or being aggressive.
They may also struggle to sympathize or empathize with others, even if they were able to before the onset of dementia. As the illness progresses, they will eventually struggle to perform basic planning tasks, problem-solve, or make decisions. It is important to remember that those with frontotemporal dementia are not in control of their actions and likely don’t recognize the impact they are having on others. They will probably find negative responses like anger, scolding, or curt redirection distressing.
