Alternate finger tapping test in patients with migraine

Area of Science:

• Neurology
• Neuroscience
• Cognitive Science

Background:

• Migraine is associated with potential cognitive dysfunction and white matter abnormalities.
• Multiple sclerosis (MS) characteristically presents with widespread white matter lesions, frequently impacting the corpus callosum.
• Subtle neurological deficits may be present in these conditions, requiring sensitive assessment tools.

Purpose of the Study:

• To evaluate the efficacy of an alternate finger tapping task (a-FTT) in detecting psychomotor dysfunction.
• To compare psychomotor performance between controls, migraine patients, and multiple sclerosis patients.
• To investigate the impact of callosal atrophy on psychomotor function in MS patients.

Main Methods:

• An alternate finger tapping task (a-FTT) administered via personal computer (PC) was used.
• Participants included healthy controls (n=41), migraine patients (n=25), and multiple sclerosis patients (n=22).
• A subgroup of five MS patients with MRI-confirmed secondary callosal atrophy was analyzed separately.

Main Results:

• Significant psychomotor slowing was observed in both migraine patients (P=0.0005) and MS patients (P<0.0001).
• The most pronounced deficits in test performance were noted in MS patients exhibiting callosal atrophy.
• The a-FTT demonstrated sensitivity in identifying minimal psychomotor dysfunction in migraine.

Conclusions:

• The PC-based a-FTT is a valuable tool for detecting subtle psychomotor impairments.
• This task can differentiate between control and patient groups, including those with migraine.
• Callosal integrity appears crucial for optimal psychomotor performance, as evidenced by MS patients with atrophy.
