Is it dementia?

My grandfather is 76 years old.
Since the beginning of December, he has frequently been unaware of what he is doing.
Initially, he could still recognize family members, but in recent days, he not only fails to recognize them but also has become very irritable, often yelling at people.
He doesn't sleep at night and shows no interest in eating, displaying strong resistance to everything.
When he is somewhat better, he talks incessantly, and his walking is unstable, as if he is about to fall.
We have consulted many doctors; some could not determine the cause (he has had an EEG), some suggested Alzheimer's disease, and others even mentioned Parkinson's disease.
We are completely at a loss regarding the cause.

Hello: Your grandfather started showing changes only in early December.
If there were no prior warning signs, this should still be considered an acute change, and organic factors cannot be ruled out.
A normal EEG does not necessarily mean there is no issue.
A detailed neurological examination or further brain CT scan is still necessary.
Regardless of the results, it may indeed be dementia, and treatment is still warranted.
It would be advisable to visit a medical center's neurology or psychiatry department for a definitive diagnosis.

More Info

Understanding dementia, particularly in seniors, can be a complex and multifaceted issue. Your grandfather's symptoms, which include confusion about his actions, mood swings, aggression, sleep disturbances, lack of appetite, and instability while walking, are concerning and warrant a thorough evaluation.

Signs and Symptoms of Dementia
Dementia is not a single disease but rather a general term that encompasses various cognitive impairments that interfere with daily life. The symptoms can vary widely depending on the type of dementia and the individual. Here are some common signs and symptoms associated with dementia:
1. Memory Loss: This is often one of the first signs. Individuals may forget recent events or conversations, and as the condition progresses, they may forget names of family members or familiar places.

2. Cognitive Decline: This includes difficulties with problem-solving, planning, or completing familiar tasks. Your grandfather's confusion about his actions may fall under this category.

3. Language Problems: Individuals may struggle to find the right words, repeat themselves, or have difficulty following or joining conversations.

4. Disorientation: People with dementia may become confused about time, place, or even their own identity. This could explain your grandfather's inability to recognize family members.

5. Mood and Behavior Changes: Dementia can lead to significant changes in personality and behavior. This includes increased agitation, aggression, or withdrawal from social interactions, which you have observed in your grandfather.

6. Physical Changes: As dementia progresses, individuals may experience physical symptoms such as difficulty walking, which can increase the risk of falls.

Diagnosis of Dementia
Diagnosing dementia involves a comprehensive assessment that includes:
1. Medical History: A thorough review of the individual's medical history, including any previous cognitive issues, family history of dementia, and current medications.

2. Physical Examination: A physical exam can help rule out other conditions that may cause similar symptoms.

3. Neurological Evaluation: This may include tests to assess memory, problem-solving, attention, language, and other cognitive abilities.

4. Imaging Tests: MRI or CT scans can help identify any structural changes in the brain that may indicate dementia or other neurological conditions.

5. Laboratory Tests: Blood tests can rule out other potential causes of cognitive decline, such as vitamin deficiencies or thyroid problems.

Types of Dementia
Given the symptoms you've described, it's essential to consider the various types of dementia:
- Alzheimer's Disease: The most common form of dementia, characterized by memory loss and cognitive decline. It often starts with mild memory issues and progresses to more severe cognitive impairment.

- Vascular Dementia: Often a result of strokes or other conditions that affect blood flow to the brain, leading to cognitive decline.

- Lewy Body Dementia: This type can include symptoms similar to both Alzheimer's and Parkinson's disease, such as visual hallucinations and motor symptoms.

- Frontotemporal Dementia: This type primarily affects personality and behavior, often leading to significant changes in social conduct.

Next Steps
Given the complexity of your grandfather's symptoms and the differing opinions from various doctors, it may be beneficial to seek a specialist in geriatric medicine or a neurologist who has experience with dementia. They can provide a more comprehensive evaluation and possibly recommend further testing, such as neuropsychological assessments or advanced imaging techniques.

In the meantime, ensuring a safe environment for your grandfather is crucial, especially considering his instability while walking. Consider implementing safety measures at home to prevent falls and ensure he has a routine that can help reduce confusion and anxiety.

Lastly, support for caregivers is essential. Caring for someone with dementia can be challenging, and seeking support groups or resources can provide valuable assistance and guidance.

In summary, understanding dementia requires a holistic approach that considers the individual's symptoms, medical history, and the potential need for specialized care. Your grandfather's situation is complex, and further evaluation is necessary to determine the underlying cause of his symptoms and to develop an appropriate care plan.
