Geriatrics addresses the health needs of older adults, focusing on frailty, dementia, falls, and chronic disease management.

The diagnostic journey for geriatric dementia is a multi-step process designed to move from broad cognitive observation to specific neurological identification. In the elderly, a diagnosis is rarely made based on a single test; instead, it is a “clinical synthesis” of the patient’s history, standardized cognitive scores, and advanced neuroimaging. The primary goal of our evaluation is to differentiate between permanent neurodegenerative diseases and reversible cognitive impairments. In seniors, conditions like severe depression, Vitamin B12 deficiency, or urinary tract infections (UTIs) can cause “Delirium” or “Pseudo-dementia,” which may mimic Alzheimer’s but are entirely treatable.
A formal evaluation begins with a baseline assessment of the patient’s “Pre-morbid Functioning”—their cognitive level before symptoms began. This provides a benchmark for measuring the severity of the decline. We also focus heavily on “Functional Assessment,” observing how the patient navigates complex environments, as this is often a more reliable indicator of dementia than memory tests alone in the early stages.
Neuropsychological testing is the “stress test” of the brain. We use standardized, validated tools to measure specific cognitive domains, including short-term memory, orientation to time and place, executive function, and language. For geriatric patients, these tests must be administered with patience and an understanding of age-related sensory changes, such as hearing or vision loss, which might otherwise skew the results.
We utilize a variety of instruments depending on the complexity of the case. The Mini-Mental State Exam (MMSE) and the Montreal Cognitive Assessment (MoCA) are common bedside tools. For a deeper analysis, a full neuropsychological battery may be conducted, which can take several hours and provides a detailed “map” of which brain regions are struggling and which are still robust.
If the screening suggests a problem, the doctor will order more advanced tests to get a clear diagnosis. These procedures look closely at the brain and the body’s systems to find the specific damage or disease causing the dementia. These detailed tests are necessary to correctly diagnose the type of Geriatric Cognitive Disorders.
Imaging is one of the most important parts of diagnosing dementia. It allows doctors to see inside the brain without surgery. Brain scans help rule out problems like a stroke, a tumor, or fluid buildup, which can sometimes be treated and fixed.
Once cognitive decline is confirmed, the next step is to find the biological “why.” Laboratory tests are used to “clean the diagnostic slate” by ruling out metabolic and infectious causes. In seniors, the brain is highly sensitive to the body’s chemistry; even a slight imbalance in electrolytes or thyroid hormones can manifest as significant confusion. These tests ensure that we do not misdiagnose a systemic medical issue as a permanent brain disease.
Structural imaging, primarily Magnetic Resonance Imaging (MRI), is used to look for physical changes in the brain’s anatomy. We look for “Atrophy” (shrinkage), specifically in the temporal lobes and the hippocampus. MRI is also vital for identifying Vascular Dementia, as it reveals “White Matter Disease” or small strokes (infarcts) that the patient may not even have realized they suffered.
There is usually not much to do to prepare for a brain scan, but following instructions is important for safety and clear images.
At LIV Hospital, we use a comprehensive approach to diagnosing Geriatric Cognitive Disorders. We do not rely on just one test. Our team of neurologists and geriatricians combines detailed history, lab tests, and advanced imaging to find the correct cause of memory loss. This careful, step-by-step process is crucial because some conditions that look like dementia can actually be fixed. Getting the right diagnosis is the first step toward finding the best way to live with the condition.
LIV Hospital is able to check for specific proteins in the spinal fluid (from a lumbar puncture) or with advanced PET scans. This level of testing helps confirm if Alzheimer’s disease is the cause of Memory Loss in Elderly patients. Being able to confirm the disease with these advanced tools is important for clinical trials and for prescribing the most targeted medicines available.

No. Brain scans are one piece of the puzzle. A diagnosis is made by combining the scan results with cognitive testing and the patient’s behavioral history.
Dementia affects personality and judgment. Understanding changes in social behavior, hygiene, or financial management helps us identify which part of the brain is being affected.
MCI is the stage between normal aging and dementia. A person with MCI has noticeable memory lapses but can still perform their daily activities. Some people with MCI stay stable, while others progress to dementia.
It can be. We often break the testing into shorter sessions to avoid “testing fatigue,” which can lead to lower scores that don’t reflect the patient’s true ability.
In almost all cases, yes. Patients have a right to know their diagnosis. Knowing the cause of their confusion often reduces their anxiety and allows them to be part of the care planning process.
