Investigating the Impact of Parathyroid Hormone (PTH): Understanding Its Role in Calcium Management and Cognitive Influence

The intricate relationship between Parathyroid Hormone (PTH), calcium levels, and cognitive functions is a fascinating aspect of human physiology. PTH, a hormone primarily responsible for regulating serum calcium levels, plays a crucial role in maintaining a balanced calcium environment in the body [3].

When calcium levels drop, PTH secretion increases to restore balance. Conversely, low calcium or dysfunctional PTH systems can lead to hypocalcemia, a condition that has neurological consequences [4].

Hypoparathyroidism, a condition characterized by low PTH levels, can cause calcium/phosphate imbalances resulting in pathological calcium deposits in brain regions such as the basal ganglia, thalamus, cerebellum, and hippocampus. These calcifications disrupt neural pathways critical for cognitive processes like memory, concentration, and motor control, leading to neurocognitive impairments, dementia, and psychiatric symptoms [1].

On the other hand, Hyperparathyroidism, a condition characterized by excessive PTH production, leads to elevated calcium levels in the blood (hypercalcemia). Some studies have found a correlation between elevated PTH levels and an increased risk of cognitive decline and dementia, including Alzheimer’s disease [6]. Symptoms of hyperparathyroidism can range from mild, such as fatigue, depression, and mental fogginess, to more severe neurological manifestations like seizures and cognitive impairment [2].

Regular monitoring and medical checkups are crucial for both conditions to ensure optimal management and to prevent long-term complications. Treatment for hypoparathyroidism typically involves calcium and vitamin D supplements, while treatment for hyperparathyroidism often involves surgical removal of the overactive parathyroid gland(s) [5].

In summary, maintaining balanced PTH and calcium levels is critical not only for skeletal and metabolic health but also for normal cognitive function and neurological integrity. PTH plays an indirect but significant role in learning by maintaining calcium balance, ensuring optimal cognitive function.
