Conventional clinical diagnosis is often delayed until after substantial neuronal degeneration has occurred. Recent advances in α-syn seed amplification assays (α-syn SAAs), including real-time quaking-induced conversion (RT-QuIC) and protein misfolding cyclic amplification (PMCA), have revolutionized PD biomarker research. These assays exploit the prion-like seeding and propagation properties of pathological α-syn to amplify trace aggregates in biological samples with exceptional sensitivity and specificity. Here, we summarize the mechanistic principles and biophysical underpinnings of α-syn SAAs, compare their diagnostic performance across biospecimens such as cerebrospinal fluid, skin, blood, and saliva, and evaluate their potential for differential diagnosis among synucleinopathies. We further discuss the integration of SAAs with other biomarkers including α-syn oligomer ELISAs, neurofilament light chain assays, and dopaminergic PET/SPECT imaging. Emerging developments, such as same-day RT-QuIC, quantitative kinetic readouts, and peripheral blood-based assays, are accelerating clinical translation. Despite challenges in assay standardization, strain discrimination, and regulatory validation, α-syn SAAs hold transformative potential for early diagnosis, patient stratification, and monitoring of therapeutic efficacy in PD.

One of the main applications for phosphonates in the brain is Alzheimer's disease, for which they can be new drug candidates and/or afford innovative strategies for diagnostics. Such applications are described in the first section of this review, which includes a large number of reports on phosphonates with cholinesterase-inhibiting activity, some recent studies exploring phosphonates for inhibiting the interaction between amyloid-β protein and alcohol dehydrogenases, and phosphonate-based materials used in proteomics-based investigative and diagnosis platforms for the different stages of development of Alzheimer's disease. The second section of the review is dedicated to ischemic brain injury and to the development of phosphonates for active against NMDA and AMPA receptors with the purpose of reducing brain damage caused by glutamate excitotoxicity. Furthermore, agonists targeting the mGlu-4 receptor suggest potential for promoting neuroregeneration.

Among these, voltage-gated calcium channels mediate various cellular activities, including muscle contraction, gene regulation, and neurotransmission. A sub-type of calcium channels are T-type calcium channels that play a critical role in regulating neuronal excitability and are essential for neurodevelopment. Mutations in genes encoding T-type calcium channels, including <i>CACNA1G</i>, <i>CACNA1H</i>, and <i>CACNA1I</i> can lead to altered channel activity, resulting in disrupted calcium entry, calcium signaling, synaptic plasticity, and neuronal differentiation. They have been implicated in a range of neurodevelopmental disorders, such as epilepsy, autism spectrum disorder, and intellectual disability. There has been considerable interest in developing blockers against T-type calcium channels to restore the dysregulated calcium homeostasis in neuronal disorders. T-type calcium channel blockers, originally developed for cardiovascular diseases, have emerged as potential therapeutic agents for neurodevelopmental disorders by targeting aberrant calcium signaling. This review explores the molecular mechanisms underlying T-type channel dysfunction caused by genetic mutations and evaluates the current evidence on the therapeutic efficacy of T-type calcium channel blockers in neurodevelopmental disorders.
