Introduction

Older people's depression is a prevalent complicated mood disorder with high rates of co-occurring medical and mental illnesses, high levels of disability, cognitive decline, and increased mortality. The risk factors for late-life depression are still poorly understood. The link between ageing and disease-related processes and depressive disorders has led to a number of pathogenic theories and therapeutic possibilities. Research into the underlying pathogenic cascade is complicated by the variety of depression, and the components implicated in late-life depression are quite different from those in early depression. Numerous vascular processes, including cerebral small artery disease, generalised microvascular dysfunction, and endothelial dysfunction, as well as metabolic risk factors including diabetes and inflammation may cause subcortical white and grey matter lesions by impairing front B-limbic and other significant neural networks, might have a role in the development of Based on their comorbidity with cerebrovascular lesions and the frequent occurrence of depression following stroke, the "vascular depression" theory hypothesises that cerebrovascular illness or vascular risk factors might predispose, trigger, and perpetuate geriatric depressive syndromes. A specific type of called vascular depression, which is characterised by decreased white matter integrity, executive dysfunction, functional disability, and a worse response to antidepressant therapy than major depressive disorder without vascular risk factors, is associated with vascular burden and cognitive deficits.

Description

Late-life depression has a multifaceted and complicated aetiology. This prevalent complicated mood disorder affects people whose first depressive episode happens beyond age and without a prior history of an affective disease Lower quality of life high comorbidity of both other mental and physical disorders, and higher mortality risk are all linked to major depression and depressive episodes in older individuals that may result in cognitive and executive impairments. Due to functional impairment, also places a significant socioeconomic burden on society by raising expenditures for healthcare and employment. Among older persons, the prevalence of major depression disorder varies greatly and ranges from of older adults report having clinically significant depressed symptoms [1].

Mild cognitive impairment patients the frequency of is rising globally, especially in lower-income nations, which is a reflection of both the general population ageing and growth. Vascular depression was reported to account for almost half of all occurrences in elderly Koreans. Elderly people often exhibit a chronic course of depressive symptoms, and older age appears to be a constant and significant risk factor for a worsening, more persistent course of depression. People with depression who are above the age of one year often experience persistent, chronic depressed symptoms. As a result, the aetiology and pathophysiology of may vary from those that are involved in infancy. Our knowledge of the neuroscience of early- and late-onset depression has significantly advanced in recent decades, and it has become clear that disruptions. Front -subcortical dysfunction brought on by vascular and other brain conditions is connected to However, the molecular foundation and its etiopathogenetic characteristics are still poorly known [2].

These obvious distinctions led to the development of mechanistic ideas about the function of metabolic and vascular risk factors and their participation in the development of it was proposed that cerebrovascular impairment, namely damage to subcortical areas of the brain, may be a factor in the development of depression in older people. "Vascular depression" or "subcortical ischemic depression" was proposed to be particularly relevant in older people without a history of prior depressive episodes and was regarded as a subtype of depression that was characterised by a distinct clinical presentation linked to cerebrovascular or related brain damage. These lesions in the subcortical white and/or grey matter were caused by reduced cerebral blood flow. Not just associated with cerebral small vessel disease, but also post-stroke sadness, depression linked to myocardial infarction.

Depression brought on by cerebral small channel disease, but also post-stroke depression, myocardial infarction depression, and depression brought on by other cardiovascular conditions. Despite the prevalence of depressive symptoms in older individuals, the idea of is still not widely understood, and it is not mentioned in the most recent psychiatric textbooks. About of adults with lifetime match the criteria for the. Major depressive disorder is described by the Diagnostic and Statistical Manual of Mental Disorders as having depressed mood or a marked loss of interest or pleasure in activities, as well as five or more of the following associated symptoms: changes in appetite or weight, changes in sleep, energy, concentration, and psychomotor activity, feelings of inappropriate guilt or worthlessness, and recurrent thoughts of death or suicide. Neurodegenerative illnesses like Alzheimer's disease are frequently accompanied by depression. Lewy body disease, Parkinson's disease, front -temporal lobe degeneration, and other conditions can all be signs of latent neurodegeneration. Even while there may not be any obvious cognitive impairment or just moderate cognitive degradation in the early stages of neurodegeneration, depressive symptoms can arise and become more severe as the disease progresses. has been linked to brain shrinkage in cross-sectional studies, especially in the hippocampus and orbitofrontal cortex. Brain atrophy may result from depression and has been linked to right frontal atrophy. It has been linked to lower brain volume, temporal lobe atrophy, and a smaller corpus callosum [3-5].

Conclusion

A prevalent mood illness in older people that responds to antidepressant treatment less favourably than does in younger people, in part because to the wide range of potential etiological and predisposing variables and the lack of universally recognised diagnostic criteria. Although there is strong evidence that generalised microvascular dysfunction, vascular risk factors like diabetes, cardiovascular disease, or hypertension, and inflammation play a part in the onset of its fundamental path mechanisms are still not fully understood, and is not currently recognised as a diagnosable mental disorder. Has typical clinical manifestations, and neuroimaging results show that has damaged the cortico frontstriatal neural pathways.
