Relationship between changes of body mass index (BMI) and cognitive decline in Parkinson's disease (PD).

Decreased BMI has been reported that it may be associated with cognitive decline in the elderly. Weight loss is common in patients with PD. However, studies comparing cognitive changes according to BMI changes in PD have not been done yet.

Association between the severity of cerebral small vessel disease, pulsatility of cerebral arteries, and brachial ankle pulse wave velocity in patients with lacunar infarction.

Background/aims: Stiff arteries cause high pulse pressure and flow to be transmitted to distal organs during systole, damaging the cerebral microvasculatures. We investigated the association between the severity of cerebral small vessel disease (CSVD), the pulsatility of cerebral arteries, and the stiffness of large arteries in patients with lacunar infarction (LI).

Methods: Subjects included 120 patients with LIs, who underwent MRI, transcranial Doppler ultrasonography, and brachial ankle pulse wave velocity (BaPWV).
