Cognitive Disorders
Cognitive disorders affect memory, thinking, and daily functioning, impacting both individuals and families. Early evaluation and proper treatment can help preserve abilities and improve quality of life.
What are Cognitive Disorders?
Cognitive disorders, also called neurocognitive disorders, are conditions that primarily affect cognitive abilities—the mental processes we use to learn, remember, solve problems, and interact with the world around us. These disorders range from mild cognitive impairment, where changes are noticeable but don't significantly interfere with daily activities, to major neurocognitive disorders like dementia, which substantially impact independent functioning. According to the Alzheimer's Association, more than 6 million Americans live with Alzheimer's disease alone, with millions more experiencing other forms of cognitive impairment.
Cognitive disorders affect multiple domains of mental functioning: memory (learning and recalling information), attention (focusing and shifting attention), executive function (planning, organizing, problem-solving), language (speaking, understanding, reading, writing), perceptual-motor abilities (recognizing objects, navigating space), and social cognition (understanding emotions and social cues). The impact extends beyond the individual—families and caregivers also experience significant challenges. At East Texas Psychiatry and Counseling, we provide comprehensive psychiatric evaluation to accurately diagnose cognitive concerns and develop appropriate treatment plans.
Early evaluation is crucial because some causes of cognitive symptoms are treatable or even reversible—including thyroid disorders, vitamin deficiencies, depression, medication side effects, and infections. Even when cognitive decline cannot be reversed, early diagnosis allows for treatment that may slow progression, addresses co-occurring symptoms like anxiety or behavioral changes, and enables families to plan for future care needs. Understanding what you're dealing with brings clarity and direction.
Schedule Your ConsultationTypes of Cognitive Disorders
Mild Cognitive Impairment (MCI)
MCI involves cognitive decline greater than expected for age but not severe enough to significantly interfere with daily activities. People may notice memory problems, word-finding difficulties, or trouble with complex tasks. MCI sometimes progresses to dementia, but not always—some people remain stable or even improve. Regular monitoring helps track changes over time.
Alzheimer's Disease
The most common cause of dementia, Alzheimer's disease involves progressive brain changes including amyloid plaques and tau tangles. It typically begins with memory problems and gradually affects other cognitive domains. Current treatments can help manage symptoms, and newer therapies targeting underlying disease processes are becoming available.
Vascular Cognitive Impairment
Caused by reduced blood flow to the brain from strokes, small vessel disease, or other vascular conditions. Symptoms depend on which brain areas are affected and may include problems with attention, processing speed, and executive function. Managing cardiovascular risk factors is crucial for prevention and treatment.
Delirium
An acute, often reversible condition involving sudden confusion, disorientation, and fluctuating attention. Delirium can be caused by infections, medications, surgery, dehydration, or other medical conditions. It requires prompt medical evaluation as the underlying cause is often treatable. Distinguishing delirium from dementia is essential for proper treatment.

Diagnosis Process
Comprehensive Clinical Assessment
Our evaluation begins with detailed medical history, review of symptoms, and information from family members who observe daily functioning. We explore the timeline of changes, their impact on independence, and any factors that might contribute to cognitive symptoms. This thorough psychiatric evaluation forms the foundation for accurate diagnosis and guides our treatment approach.
Cognitive Testing & Screening
We use standardized cognitive assessments that evaluate multiple domains: memory, attention, language, visuospatial abilities, and executive function. These tests help determine which cognitive areas are affected, the severity of impairment, and provide a baseline to track changes over time. Testing is conducted in a comfortable, supportive environment.
Differential Diagnosis & Medical Workup
We identify or rule out treatable causes of cognitive symptoms including depression (which can mimic dementia), thyroid disorders, vitamin deficiencies, medication effects, sleep disorders, and infections. We coordinate with primary care providers and specialists for laboratory testing and brain imaging when indicated to ensure comprehensive evaluation.

Common Questions About Cognitive Disorders
Diagnosis involves comprehensive psychiatric evaluation including detailed medical history, cognitive testing, physical examination, and often laboratory tests and brain imaging. We assess memory, attention, language, problem-solving, and visuospatial abilities using standardized tests. Information from family members about observed changes is also crucial. The goal is to determine the type and severity of cognitive impairment and identify any treatable underlying causes.
Causes vary by type. Alzheimer's disease involves brain changes including amyloid plaques and tau tangles, with genetic and age-related factors. Vascular dementia results from reduced blood flow due to strokes or small vessel disease. Other causes include Lewy body disease, frontotemporal degeneration, Parkinson's disease, head injuries, infections, alcohol use, and nutritional deficiencies. Some causes are reversible—including thyroid disorders, vitamin B12 deficiency, depression, medication effects, and certain infections—making thorough evaluation essential.
Treatment depends on the underlying cause. For reversible causes, addressing the underlying condition (treating thyroid disease, replacing vitamins, adjusting medications, treating depression) can improve cognition. For Alzheimer's disease, medications like cholinesterase inhibitors and memantine help manage symptoms. Newer monoclonal antibody treatments targeting amyloid plaques are available for early-stage Alzheimer's. Medication management also addresses behavioral symptoms like anxiety, agitation, sleep problems, and depression that commonly accompany cognitive disorders. Cognitive rehabilitation and caregiver support are also important components.
Some cognitive impairment is potentially reversible when caused by treatable conditions—such as thyroid disorders, vitamin B12 or folate deficiency, depression ("pseudodementia"), medication side effects, normal pressure hydrocephalus, or certain infections. This is why comprehensive evaluation to identify treatable causes is so important. Progressive dementias like Alzheimer's disease cannot currently be cured, but treatment can slow progression, manage symptoms, and significantly improve quality of life. Newer disease-modifying treatments offer hope for early-stage Alzheimer's. Early diagnosis and intervention are crucial regardless of the cause.
Cholinesterase inhibitors (donepezil, rivastigmine, galantamine) are commonly used for mild to moderate Alzheimer's disease and may help other dementias. They work by increasing levels of a chemical messenger important for memory. Memantine, which works differently, is used for moderate to severe Alzheimer's. Newer monoclonal antibody treatments (lecanemab, donanemab) target amyloid plaques in early-stage Alzheimer's. Additional medications address common accompanying symptoms: antidepressants for depression, medications for anxiety or agitation, and treatments for sleep problems. Our medication management approach individualizes treatment based on each person's specific needs.
Yes, the relationship between cognitive disorders and other mental health conditions is complex and bidirectional. Depression is extremely common in people with cognitive disorders—affecting up to 40% of those with dementia. Depression can also cause cognitive symptoms that mimic dementia (sometimes called "pseudodementia"). Anxiety disorders frequently co-occur and can worsen cognitive symptoms. Psychosis, including delusions and hallucinations, occurs in many people with dementia. Behavioral changes like agitation, apathy, and irritability are common. Comprehensive evaluation distinguishes between these conditions and addresses all factors affecting functioning.
Seek evaluation if you or a loved one experiences memory problems that affect daily life, difficulty completing familiar tasks like cooking or managing finances, confusion about time or place, trouble following or joining conversations, misplacing things and being unable to retrace steps, changes in judgment or decision-making, withdrawal from work or social activities, personality or mood changes, or if family members express concern about cognitive changes. Don't dismiss symptoms as "just aging"—while some memory changes are normal with age, significant changes warrant evaluation. Early diagnosis can identify treatable causes and enables better planning. Call 430-288-5800 to schedule a consultation.
