Summary
Diabetes mellitus and depression significantly worsen cognitive function, particularly sensomotoric skills. Early diagnosis through sensomotoric testing is crucial for detecting central nervous system damage in diabetic patients.
Area of Science:
- Neuroscience
- Endocrinology
- Psychiatry
Background:
- Hyperglycemia in diabetes mellitus (DM) is a primary driver of cognitive disorders.
- Cerebral insulin deficiency exacerbates cognitive impairment, affecting somatosensoric functions.
- Comorbid depression intensifies cognitive deficits in diabetic individuals.
Purpose of the Study:
- To investigate the impact of diabetes mellitus and depression on cognitive functions, specifically sensomotoric skills.
- To evaluate the potential of sensomotoric skill assessment for early diagnosis of CNS disorders in DM.
- To explore the interaction between metabolic dysregulation in DM and depression on cognitive impairment.
Main Methods:
- Cognitive functions, particularly sensomotoric skills, were assessed using the SPS-2001E apparatus.
- Three groups were studied: healthy subjects, diabetic patients with depression, and depressive patients without DM (aged 37-52).
- Beck Depression Inventory (BDI) and HbA1c levels were used to quantify depression severity and glycemic control.
Main Results:
- Early-stage DM showed mild sensomotoric cognitive disorders, worsening with increased BDI scores and HbA1c.
- Depressive patients with DM exhibited significantly more pronounced sensomotoric cognitive disorders than those without DM (p<0.001).
- Cognitive impairment intensified progressively from subgroup IA to IC, correlating with BDI and HbA1c levels.
Conclusions:
- The co-occurrence of depression and DM exacerbates cognitive impairment through mutual interactions.
- Sensomotoric skill assessment can serve as a valuable screening tool for early detection of CNS disorders in DM.
- Investigating sensomotoric skills is vital for the early diagnosis of nervous system damage associated with diabetes mellitus.

01:25Type II Diabetes Mellitus III: Clinical Manifestations and Diagnosis
Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated hypertension...
01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:19Type I Diabetes III: Clinical Manifestations
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:18Depression: Overview
Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
01:27Depressive Disorders: MDD and Dysthymia
Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...
