When do I consult a doctor for Alzheimer’s disease?
How is Alzheimer’s disease diagnosed?
Your doctor will ask you about your symptoms, your family history and any other medical conditions you may have. This is called history taking, and it helps your physician rule out other causes and narrow down the diagnosis. History taking is followed by –
- Physical and neurological evaluation: Test for muscle tone and strength, sight and hearing senses, reflexes, coordination, and balance
- Blood tests: To rule out other possible causes of confusion or memory loss, such as thyroid disease or a vitamin deficiency
- Mental status and neuropsychological assessment: To evaluate memory and mental functioning
- Brain imaging: CT, MRI or PET scan to detect Alzheimer’s related changes and also rule out any other disease
How can I prevent the progress of Alzheimer’s disease?
What is the treatment for Alzheimer’s disease?
Alzheimer’s disease is a progressive condition. The treatment options available are intended to arrest the progress and to help cope with the disease. These include –
- Medicines (help in slowing the progression of the disease)
- Cognitive stimulation therapy: Group exercises and activities that are intended to improve memory and problem-solving skills
- Cognitive rehabilitation: This involves working with a therapist or caregiver to accomplish a personal goal, like learning to use a mobile phone or other commonplace chores
How do I care for a loved one suffering from Alzheimer's disease?
The most important aspect of caregiving is to be understanding, supportive, and patient with your loved one. You can –
- Make sure they take their medications on time
- Assess their daily routine and what tasks they are able to complete
- Save important phone numbers and enable location tracking on their mobile phones to easily locate them in case they get lost

- Test the food’s temperature because your loved one might not be able to tell whether the food or drink is too hot or cold. Always check the temperature before serving

Memory loss and other cognitive impairments brought can impact the treatment of other medical conditions. A person with Alzheimer’s may not be able to –
- Communicate the symptoms of other illnesses
- Adhere exactly to the medicine and treatment instructions
- Identify the side-effects of medicines
Other complications include:
- Pneumonia or other infections
Can Alzheimer’s disease lead to death?
