Introduction:

With the demographic and epidemiological transition, the prevalence of neurological pathologies is expected to increase. In particular, Colombia does not have updated indicators regarding the frequency of these diseases.

Objective:

To determine the prevalence of ten relevant neurological pathologies (migraine, epilepsy, Alzheimer>s disease, ischemic and hemorrhagic stroke, Parkinson>s disease, multiple sclerosis, myasthenia gravis, meningitis, Guillain-Barre syndrome and motor neuron disease) in patients aged ≥15 years between 2015-2017.

Materials and methods:

Cross-sectional study of administrative sources, based on the Individual Service Provision Registries (RIPS) consolidated by the Ministry of Health. The available socio- demographic characteristics (sex, age group, health regime, origin, etc.) were analyzed, and the obtained prevalences were adjusted according to the distributions of the world and national population.

Results:

For 2017, the prevalences adjusted to the world age distribution, per 100,000 inhabitants, were: migraine 2170 (95%CI 2164-2176); epilepsy 586 (95%CI 583-589); Alzheimer>s disease 387 (95%CI 384-389); stroke 263 (95%CI 260-265), specifically, ischemic 136 (95%CI 134137) and hemorrhagic (95%CI 95-98); Parkinson's disease 91 (95%CI 90-93), multiple sclerosis 19 (95%CI 1819); myasthenia gravis 11 (95%CI 11-11); meningitis 10 (95%CI 9-10); Guillain-Barre syndrome 9 (95%CI 8-9); and motor neuron disease 6 (95%CI 5-6). The 2015-2017 median variation was 19.38%.

Conclusion:

The most prevalent pathologies nationwide, in order of frequency, were migraine, epilepsy, and Alzheimer>s disease.
