## **Stages of Dementia**
Dementia typically progresses in **three stages**—though not all individuals experience symptoms in the same sequence or severity.
### **Early Stage (Mild Dementia)**
* Minor memory lapses
* Slight changes in personality
* Difficulty with complex tasks
* Increased effort to maintain normalcy
### **Middle Stage (Moderate Dementia)**
* Worsening memory loss
* Disorientation and confusion
* Behavior and mood disturbances
* Need for assistance with daily activities
### **Late Stage (Severe Dementia)**
* Significant communication difficulties
* Loss of physical abilities (walking, swallowing)
* Near-complete dependence on caregivers
* Increased risk of infections, especially pneumonia
—
## **Different Types of Dementia and Their Specific Symptoms**
### **Alzheimer’s Disease**
* Most common form of dementia (60–80% of cases)
* Hallmark symptom: gradual memory loss
* Beta-amyloid plaques and tau tangles damage brain cells
### **Vascular Dementia**
* Caused by reduced blood flow to the brain, often after a stroke
* Symptoms may appear suddenly
* Problems with judgment, planning, and attention are more prominent
### **Lewy Body Dementia**
* Includes symptoms like visual hallucinations, motor impairment, and fluctuating cognition
* Often misdiagnosed as Parkinson’s disease
### **Frontotemporal Dementia (FTD)**
* Affects personality, behavior, and language before memory
* Can lead to socially inappropriate behavior and speech loss
—
## **Risk Factors for Dementia**
### **Non-Modifiable Risk Factors:**
* Age (risk increases significantly after age 65)
* Family history or genetic predisposition
* History of head injury
### **Modifiable Risk Factors:**
* Poor cardiovascular health
* Diabetes or high cholesterol
* Smoking and alcohol use
* Depression and social isolation
* Lack of mental or physical activity
—
## **When to Seek Medical Help**
Many older adults experience some memory lapses, but persistent or worsening cognitive issues should be evaluated by a healthcare provider. Early diagnosis helps in:
* Planning care
* Slowing progression
* Accessing support services
* Managing symptoms effectively

## **Diagnostic Process**
### **1. Medical History Review**
Doctors will assess the person’s history of symptoms, lifestyle, medications, and family background.
### **2. Cognitive and Neuropsychological Tests**
These tests evaluate memory, problem-solving, language, and attention.
### **3. Physical and Neurological Exams**
Doctors look for signs of stroke, Parkinson’s, or other physical conditions.
### **4. Brain Imaging (CT, MRI, or PET scans)**
Used to detect brain shrinkage, blood vessel damage, tumors, or structural abnormalities.
### **5. Blood Tests**
Rule out infections, vitamin deficiencies, or metabolic issues that can mimic dementia.
