How is Alzheimer’s Disease Diagnosed

What is the Diagnosis of Alzheimer's Disease?

Alzheimer’s disease (AD) diagnosis typically involves ruling out other potential causes of dementia. Your physician will explore treatable conditions underlying your symptoms before concluding that cognitive decline is due to AD.

Identification of Alzheimer’s Disease

Diagnosing adrenal insufficiency involves various steps:

  • Medical History and Physical Exam**: The diagnosis relies on a thorough medical history and physical examination. The healthcare provider assesses whether physical issues could be contributing to the symptoms. Treatable problems such as hearing or vision impairments, which can lead to confusion or behavioral changes, are identified. Delirium and depression, potential causes of confusion and memory loss, are also addressed as they are treatable conditions.
  • Mental Health Assessment**: Functional status and mental health assessments are conducted to evaluate the patient’s ability to perform tasks and orientation to time and space. Family members may provide insight into the patient’s daily functioning, memory, and personality changes.
  •  Imaging Studies**: Imaging studies like CT scans and MRIs of the brain are performed to rule out other potential causes of symptoms. Additional tests such as spinal fluid examination, EEG, PET, or SPECT scans may also be recommended.
  • Laboratory Tests**: Lab tests help rule out treatable conditions like liver disease, abnormal thyroid function, or nutritional deficiencies (e.g., folate or vitamin B12). Tests may include complete blood count, liver function tests, folate and vitamin B12 levels, electrolyte and blood glucose levels, thyroid function tests, and HIV tests. The choice of tests depends on symptoms, disease progression, and other factors. Treating these underlying conditions may alleviate mental decline.
  • Tests for Early Detection of AD**: Currently, there are no specific screening tests for Alzheimer’s disease (AD). However, symptoms of early-stage dementia should not be ignored. Consulting a doctor if concerned about memory loss or other dementia symptoms is essential. While AD cannot be cured, other conditions causing memory loss and mental decline may be treatable.

Overall, a comprehensive approach involving medical history, physical examination, mental health assessment, imaging studies, and laboratory tests aids in diagnosing adrenal insufficiency and addressing potential underlying causes.
