Dementia:
The brain function affected depends on what?
The brain function affected depends on the type of dementia
Dementia
Pathophysiology for Dementias in general :
includes what?
Neuronal Death:
Neurotransmitter Changes:
Structural Brain Changes:
Inflammation:
Dementia
Pathophysiology for Dementias in general :
Neuronal death: Most forms of dementia involve what?
Neuronal Death: Most forms of dementia involve the death of nerve cells (neurons) in the brain.
Dementia
Pathophysiology for Dementias in general :
Neurotransmitter Changes: What occurs with this?
The levels or functioning of chemicals that nerve cells use to communicate (neurotransmitters) may be altered.
Dementia
Pathophysiology for Dementias in general :
Structural Brain Changes: What occurs with this?
Over time, specific areas of the brain may shrink (atrophy) in some types of dementia.
Dementia
Pathophysiology for Dementias in general :
Inflammation: What occurs with this?
Some dementias, including AD, involve inflammatory processes in the brain.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
includes:
Amyloid Plaques:
Neurofibrillary Tangles:
Neurotransmitter Disruption:
Brain Atrophy:
Inflammation:
Oxidative Stress:
Vascular Factors:
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Amyloid Plaques: What is the hall mark of AD? What do plaques do?
A hallmark of AD is the accumulation of beta-amyloid peptides, which clump together to form plaques in spaces between neurons.
These plaques are believed to block cell-to-cell signaling and trigger an immune response that can lead to inflammation and further damage.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Neurofibrillary Tangles: Inside neurons, what is a characteristic feature?
Inside the neurons, another characteristic feature of AD is the presence of neurofibrillary tangles.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Neurofibrillary Tangles: What are tangles made from?
These tangles are made of a protein called tau.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Neurofibrillary Tangles: In AD, what happens to Tau?
In AD, tau undergoes chemical changes that cause it to form twisted tangles, leading to transport problems inside the neurons and eventual neuron death.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Neurotransmitter Disruption: As AD progresses, what happens?
As AD progresses, there’s a decrease in the level of the neurotransmitter acetylcholine, which plays a vital role in memory and attention.
The neurons that produce acetylcholine are damaged and lost in AD.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Brain Atrophy: What happens with the damage in AD? What is the first region to be affected?
Over time, the damage in AD spreads, and there’s a marked shrinkage (atrophy) of brain tissue.
The hippocampus, crucial for memory formation, is usually the first region to be affected.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Inflammation: What becomes activated in AD? What do they release?
Glial cells, which support neuron function, become activated in AD and release inflammatory molecules that contribute to damage.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Oxidative Stress:
There’s evidence that oxidative stress plays a role in AD.
Reactive oxygen species (free radicals) can damage neurons and are found in higher levels in the brains of people with AD.
Dementia
Pathophysiology of Alzheimer’s Disease (AD):
Vascular factors: What may contribute to AD progression
Reduced blood flow, microbleeds, and other vascular changes may contribute to AD progression.
Dementia:
What are the types of dementia?
- Alzheimer’s Disease (AD)
- Vascular Dementia
- Lewy Body Dementia
- Frontotemporal Dementia
- Parkinson’s Disease Dementia
Dementia:
Alzheimer’s Disease (AD): Presentation
Patients often present with memory loss as an early symptom.
As AD progresses, other areas of the brain are affected leading to challenges in reasoning, visual spatial abilities, and eventually, speech and movement.
Dementia:
Alzheimer’s Disease (AD): Areas of the brain affected
Alzheimer’s primarily impacts the hippocampus, especially in the early stages.
The hippocampus is involved in memory formation.
Dementia:
Vascular Dementia: Areas of the Brain Affected
Why does this form of dementia arise?
This form of dementia arises due to reduced blood flow to various parts of the brain.
Dementia:
Vascular Dementia: Areas of the Brain Affected
The specific regions affected depend on the blood vessels that are blocked or damaged.
Dementia:
Vascular Dementia: Presentation
How do symptoms appear? What are they? How is progression?
Symptoms can be sudden if they are due to a stroke.
They might include confusion, difficulty speaking, or weakness on one side of the body.
The progression can be step-wise, with periods of stability followed by sudden declines.
Dementia:
Lewy Body Dementia (LBD): Areas of the Brain Affected
LBD is associated with abnormal protein deposits (Lewy bodies) that form in various parts of the brain, including the cortex and brainstem.
Dementia:
Lewy Body Dementia (LBD):
Presentation:
Beyond memory and cognitive challenges, LBD often involves visual hallucinations, Parkinsonian movement symptoms (like rigidity or shuffling walk), and fluctuations in alertness.
Dementia:
Frontotemporal Dementia (FTD):
Areas of the Brain Affected:
As the name suggests, FTD affects the frontal and temporal lobes of the brain.
Dementia:
Frontotemporal Dementia (FTD):
Areas of the Brain Affected: As the name suggests, FTD affects the frontal and temporal lobes of the brain.
These regions are associated with what?
These regions are associated with personality, behavior, and language.
Dementia:
Frontotemporal Dementia (FTD):
Presentation: How does it begin? How may patients act?
Presentation: Unlike other dementias that start with memory problems, FTD often begins with behavioral changes or language disturbances.
Patients might act inappropriately or impulsively, show apathy, or exhibit speech difficulties.
Dementia
Parkinson’s Disease Dementia (PDD)
Areas of the Brain Affected:
This type of dementia arises in the context of Parkinson’s disease, which primarily affects the basal ganglia and substantia nigra, regions associated with movement.
However, over time, other brain regions become involved.
Dementia
Parkinson’s Disease Dementia (PDD)
Presentation: When does it present? What symptoms?
This dementia typically occurs after a person has had Parkinson’s disease for some time.
Beyond the motor symptoms (like tremors, rigidity), individuals might show slowed thinking, difficulty concentrating, and visual hallucinations.
