Variante 11A: 60-Year-Old Woman Suffers From Arterial Hypert

Variante 11 A 60 Year Old Women Suffers From Arterial Hypertension A

A 60-year-old woman with a history of arterial hypertension for approximately 15 years presents with cognitive decline following her second stroke. She reports an unexplained decrease in mood, impaired concentration, forgetfulness about recent events, and difficulty recalling past occurrences. CT imaging reveals postinfarction changes in the posterior frontal cortical areas. Based on these findings, the most probable diagnosis is vascular dementia.

Vascular dementia is a common neurocognitive disorder resulting from cerebrovascular pathology, particularly when multiple infarcts or ischemic lesions impair cognitive functions. In this patient's case, her history of hypertension and stroke, combined with neuroimaging evidence showing infarction in specific cortical regions, aligns with vascular dementia's clinical and radiological profile (O'Brien & Thomas, 2015). It is characterized by a stepwise decline in cognitive abilities, often with prominent executive dysfunction, associated with vascular risk factors (Saver, 2014).

Other options such as Alzheimer's disease typically show a gradual decline mainly affecting memory initially, with neuroimaging revealing hippocampal and cortical atrophy without lacunar infarcts (Hampel et al., 2018). Huntington's disease involves a genetic mutation with motor symptoms and cognitive decline but is less associated with cerebrovascular lesions (Walker, 2007). Pick's disease (primary progressive aphasia) affects language predominantly and shows frontotemporal atrophy (Seelaar et al., 2011), while dissociative amnesia is a psychological condition without structural brain changes or corresponding neuroimaging findings (van der Kolk et al., 2014).

Vascular dementia remains one of the most prevalent forms of dementing illnesses, especially in older patients with vascular risk factors such as hypertension. Its diagnosis involves clinical assessment supported by neuroimaging findings that demonstrate cerebrovascular lesions (O'Brien & Thomas, 2015). The case presented exemplifies this connection, with the patient's history of hypertension and stroke, along with CT findings showing postinfarction changes, strongly indicating vascular etiology.

Pathophysiologically, vascular dementia results from ischemic injury to brain tissue, disrupting neural circuits responsible for cognition, executive functions, and behavior (Saver, 2014). The gradual yet stepwise deterioration differentiates it from other dementias like Alzheimer's disease, which typically have a more insidious onset (Hampel et al., 2018). Vascular lesions may coexist with Alzheimer pathology, further complicating the clinical picture (Janssen et al., 2013), but the key diagnostic features in this case point toward vascular dementia.

In the neuropsychological profile, patients usually display deficits in planning, organizing, and problem-solving, along with memory impairment. The location of infarcts influences the manifestation; for instance, posterior frontal cortical damage can affect executive functions and attention, as seen in this patient. Management focuses on controlling vascular risk factors, preventing further infarcts, and supportive cognitive therapies (O'Brien & Thomas, 2015). Pharmacologically, cholinesterase inhibitors may be used off-label, although their efficacy is limited compared to Alzheimer's disease (Gorelick et al., 2011).

Preventive strategies emphasizing blood pressure control, lipid management, and lifestyle modifications are crucial for reducing the risk of vascular dementia (Sachdev et al., 2014). Advances in neuroimaging techniques, including MRI, help delineate the extent of cerebrovascular pathology and aid in diagnosis and prognosis (Janssen et al., 2013). Overall, recognizing the clinical context, risk factors, and neuroimaging features allows healthcare providers to diagnose vascular dementia accurately and tailor treatment accordingly.
