Depression frequently coexists with dementia, although in many cases the depression is not recognized clinically. Depression represents a major additional burden in dementia, not only for the patients but also for families, caregivers, and, economically, society as a whole. However, depression in patients with dementia does respond to treatment, and appropriate therapy can significantly improve the well-being of these patients. Depression in patients with dementia is currently treated with a variety of standard antidepressive agents (tricyclic antidepressants, selective serotonin reuptake inhibitors, monoamine oxidase inhibitors), but none is free from significant side effects. Moreover, the use of these drugs is often complicated by a number of age-related factors or effects on the cholinergic neurotransmitter system. Consequently, an antidementia treatment with concomitant antidepressive properties and an acceptable benefit/risk ratio would represent an attractive therapeutic option. The pathogenesis of depression in patients with dementia is not well understood, but may be related to increased intracellular calcium ions in the CNS, the so-called "calcium hypothesis." This hypothesis may explain why some calcium antagonists exert psychotropic effects, including putative antidepressant activity. Animal models and clinical data provide support for the use of calcium channel antagonists for the treatment of depression, with the potential for good tolerability. The latter aspect is especially important for elderly patients with dementia. Although antidepressive effects have been seen with a number of calcium channel antagonists, the dihydropyridine derivative nimodipine shows particular potential for clinical use, perhaps because nimodipine is one of the most lipophilic of these drugs and therefore achieves high concentrations in the CNS, and because of the unique biochemical properties of the dihydropyridine compounds compared with other L type calcium channel blockers. Nimodipine also increases somatostatin levels in CSF, one of the cardinal biochemical deficits in Alzheimer's disease. Data obtained incidentally from the use of nimodipine in the treatment of elderly demented patients clearly demonstrate significant antidepressant activity by the drug in this patient group. Formal clinical evaluation is therefore recommended to establish more clearly the therapeutic benefits offered by nimodipine in patients who suffer from both dementia and depression.

Melatonin (N-acetyl-5-methoxytryptamine, MLT), the main hormone produced by the pineal gland, not only regulates circadian rhythm, but also has antioxidant, anti-ageing and immunomodulatory properties. MLT plays an important role in blood composition, medullary dynamics, platelet genesis, vessel endothelia, and in platelet aggregation, leukocyte formula regulation and hemoglobin synthesis. Its significant atoxic, apoptotic, oncostatic, angiogenetic, differentiating and antiproliferative properties against all solid and liquid tumors have also been documented. Thanks, in fact, to its considerable functional versatility, MLT can exert both direct and indirect anticancer effects in factorial synergy with other differentiating, antiproliferative, immunomodulating and trophic molecules that form part of the anticancer treatment formulated by Luigi Di Bella (Di Bella Method, DBM: somatostatin, retinoids, ascorbic acid, vitamin D3, prolactin inhibitors, chondroitin-sulfate). The interaction between MLT and the DBM molecules counters the multiple processes that characterize the neoplastic phenotype (induction, promotion, progression and/or dissemination, tumoral mutation). All these particular characteristics suggest the use of MLT in oncological diseases.
