Stiff-person syndrome: case series.

Area of Science:

• Neurology
• Immunology

Background:

• Stiff-person syndrome (SPS) is a rare autoimmune neurological disorder.
• It is characterized by progressive muscular rigidity and spasms.
• Glutamic acid decarboxylase (GAD) antibodies are implicated in SPS pathogenesis and associated with other autoimmune diseases.

Purpose of the Study:

• To report three cases of classical Stiff-person syndrome.
• To confirm the diagnosis through high serum GAD antibody levels.
• To evaluate treatment responses to specific therapies.

Main Methods:

• Case study of three patients with classical SPS.
• Confirmation of diagnosis via high serum GAD antibody levels.
• Monitoring patient response to gamma amino butyric acid-enhancing drugs and immunotherapies.

Main Results:

• All three patients presented with classical SPS symptoms.
• High serum levels of GAD antibodies confirmed the diagnosis in all cases.
• Patients showed favorable responses to GABA-enhancing drugs and immunotherapies.

Conclusions:

• High serum GAD antibodies are a key diagnostic marker for Stiff-person syndrome.
• Gamma amino butyric acid-enhancing drugs and immunotherapies are effective treatments for SPS.
• Early diagnosis and appropriate treatment can lead to positive patient outcomes in SPS.
