Is My Father-in-Law Suffering from Dementia? Cognitive Decline

Suspecting that my father-in-law has dementia?

Hello, Dr.
Lin.
My father-in-law is 75 years old and has been taking medication for hypertension, diabetes, and heart disease for a long time.
Last year, he started taking Parkinson's disease medication due to symptoms of tremors in his limbs.
In February of this year, he fell and was sent to the hospital due to general weakness, where he was diagnosed with a secondary stroke.
Prior to this, he was able to take care of himself and communicate with family members, but since then, the degree of cognitive decline has been difficult to accept.
This stroke did not cause mobility issues, but he has exhibited symptoms of cognitive decline, such as not recognizing family members, experiencing delusions, having disrupted sleep-wake cycles, and often seeming to be disconnected from the present time and space.
During a follow-up visit, I asked the neurologist if it could be a possibility of dementia, but the neurologist only indicated it was cognitive decline.
While it is true that elderly individuals do experience decline, the deterioration seems to be quite severe.
Should we consider a consultation with a psychiatrist? If it is indeed dementia, we hope he can start medication treatment as soon as possible.

Hello Ms.
Chen, it appears that your father-in-law is indeed exhibiting significant psychiatric symptoms, which could be a result of a stroke.
Additionally, these symptoms may also be caused by antiparkinsonian medications or a state of delirium due to physical illness or treatment, leading to altered levels of consciousness.
Furthermore, some elderly individuals may experience dementia resulting from a stroke, which can be compounded by Alzheimer's disease.
Dementia itself has a high prevalence of associated psychiatric symptoms.
In summary, given the evident delusions and sleep issues, psychiatric treatment should be considered necessary.

It sounds like your father-in-law is experiencing significant cognitive decline, which can be concerning for both him and the family. Given his medical history, including hypertension, diabetes, and heart disease, as well as the recent strokes, it is not uncommon for elderly individuals to experience cognitive changes. The symptoms you describe—such as not recognizing family members, experiencing delusions, and having disrupted sleep patterns—are indeed indicative of potential dementia or other forms of cognitive impairment.

Dementia is an umbrella term that encompasses various types of cognitive decline, including Alzheimer's disease, vascular dementia (which can occur after strokes), and Lewy body dementia, among others. Each type has its own set of characteristics, but common symptoms include memory loss, confusion, difficulty with language, and changes in mood or behavior. The fact that your father-in-law has had strokes raises the possibility of vascular dementia, which can result from reduced blood flow to the brain.

The rapid decline in cognitive function you mentioned following the second stroke is particularly concerning. It is not unusual for a stroke to exacerbate existing cognitive issues or to trigger new ones. The brain's ability to recover from such events varies greatly among individuals, and some may experience significant changes in their cognitive abilities afterward.

Regarding your question about whether he should see a psychiatrist, it may be beneficial for him to be evaluated by a mental health professional, especially if there are concerns about his mental state, such as delusions or severe mood changes. A psychiatrist can assess his cognitive function and emotional well-being, and they may recommend appropriate treatments, including medications that can help manage symptoms of dementia or related conditions.

In terms of treatment, if dementia is diagnosed, there are medications available that can help manage symptoms or slow the progression of certain types of dementia. These medications, such as cholinesterase inhibitors (e.g., donepezil, rivastigmine) and memantine, can be beneficial for some patients, particularly in the early to moderate stages of Alzheimer's disease. However, the effectiveness of these medications can vary, and they are not a cure.

Additionally, it is essential to consider non-pharmacological interventions, such as cognitive rehabilitation, occupational therapy, and creating a supportive environment that promotes safety and engagement. Engaging your father-in-law in social activities, maintaining a routine, and providing mental stimulation can also be beneficial.

It is crucial to communicate openly with his healthcare providers about your concerns and to advocate for a comprehensive evaluation. If you feel that his current medical team is not addressing your concerns adequately, seeking a second opinion from a neurologist or geriatrician who specializes in cognitive disorders may be a good step.

In summary, your father-in-law's symptoms warrant further evaluation for dementia or other cognitive impairments. A multidisciplinary approach involving neurologists, psychiatrists, and geriatric specialists can provide a comprehensive assessment and management plan tailored to his needs. Early diagnosis and intervention can significantly impact the quality of life for both him and your family.
