CIEN participates in the 78th Annual Meeting of the Spanish Society of Neurology

The Centre for Research in Neurological Diseases (CIEN) will take part in the 78th Annual Meeting of the Spanish Society of Neurology (SEN), to be held in Seville from 17 to 21 November 2026, with six oral communications, four posters and several contributions from its researchers in panels and debate sessions.

Oral communications

The programme includes six oral communications involving CIEN researchers:

• Thursday 19 November, 09:50–09:58. “Longitudinal patterns of cerebral hypometabolism in limbic-predominant age-related TDP-43 encephalopathy and autopsy-confirmed Alzheimer’s disease” (23598). Session: Behaviour and Dementia II. Authors: Miguel A. Labrador Espinosa et al.
• Thursday 19 November, 11:00–11:08. “Enlarged perivascular spaces in the centrum semiovale reflect the severity of cerebral amyloid angiopathy in Alzheimer’s disease” (23410). Session: Behaviour and Dementia III. Authors: Mario E. Ricciardi et al.
• Thursday 19 November, 12:00–12:08. “Baseline and longitudinal brain atrophy in cognitively healthy individuals with elevated plasma p-tau217 levels” (23581). Session: Behaviour and Dementia III. Authors: Michel Grothe et al.
• Thursday 19 November, 16:20–16:40. “Time will tell: multigenerational brain donation in familial Alzheimer’s disease”. Session: Spanish Neuropathology Club (affiliated society). Research in Neuropathology. Authors: Alberto Rábano et al.

Posters

The CIEN Foundation’s participation also includes four posters:

• Tuesday 17 November: “Baseline sleep fragmentation measured by actigraphy and its cross-sectional relationship with the plasma Aβ42/40 ratio and NfL protein in healthy older adults” (23568). Session: Behaviour and Dementia P1. Authors: Meritxell Valentí Soler et al.
• Tuesday 17 November: “Longitudinal sleep trajectory measured by actigraphy and its dynamic association with plasma biomarkers of axonal damage and neuroinflammation in healthy ageing” (24722). Session: Behaviour and Dementia P1. Authors: Meritxell Valentí Soler et al.
• Wednesday 18 November: “Madrid-FTD. Building a frontotemporal dementia (FTD) study cohort for the validation of cutting-edge markers” (24244). Session: Behaviour and Dementia P3. Authors: María Ascensión Zea Sevilla et al.
• Wednesday 18 November: “Clinical and neuropsychological characterisation and longitudinal trajectory of a cohort of patients with essential tremor (ET)” (24820). Session: Behaviour and Dementia P3. Authors: Belén Frades Payo et al.

Participation in scientific sessions

In addition to the communications, several CIEN researchers will play a prominent role in the scientific programme.

On Wednesday 18 November, Pascual Sánchez-Juan will chair Panel 1 of the Behaviour and Dementia Study Group, devoted to biomarkers of neurodegenerative diseases other than Alzheimer’s disease (08:30–10:30). In the same session, Aitana Sogorb-Esteve will give the talk “Update on biochemical biomarkers in FTLD” (09:00–09:30).

On Thursday 19 November, Teodoro del Ser Quijano will chair the Behaviour and Dementia II session (08:00–10:00).

That same day, Pascual Sánchez-Juan will deliver the Dr Luis Barraquer Ferré Lecture, entitled “Can we predict Alzheimer’s decades before symptoms appear?”, scheduled from 11:00 to 11:30. He will also take part as an expert in the debate “Neurodegenerative diseases against the clock”, scheduled from 16:00 to 17:30.

Participation in this annual meeting strengthens CIEN’s presence in the leading forums for scientific exchange in neurology and provides an opportunity to share the progress of its research platforms in the study of neurodegenerative diseases.
