Study Notes

Organization of the Nervous System

Comprises the brain, spinal cord, and a complex nerve network.
Responsible for communication between the brain and body.

Neurological Thinking

Diagnosis relies on background knowledge of neurological symptoms and clinical features.
Techniques involve history-taking and neurological examination.
Synthesis of data leads to effective neurological reasoning.

Symptoms and Signs

Common symptoms include headache, seizures, weakness, and sensory changes.
Important clinical features rated in Indonesian medical competency standards.

Pathological Processes in Neurology

Systemic: Includes metabolic, toxic, nutritional, and endocrine disorders.
Vascular: Covers hemorrhages and infarctions.
Infectious: Encompasses viral, bacterial (like meningitis), and parasitic infections.
Neoplastic: Refers to primary and secondary tumors along with paraneoplastic syndromes.
Degenerative: Exemplified by Huntington's disease.
Immunological: Conditions like Guillain-Barré Syndrome (GBS) and Multiple Sclerosis (MS).

Clinical Examination

Anamnesis accounts for 60-75% of the diagnosis.
Physical examination contributes 20-30%.
Diagnostic imaging and support contribute about 10%.

Lesions Indications

Upper Motor Neuron (UMN) lesions: Show hypertonia, hyperreflexia, and absence of muscle atrophy.
Lower Motor Neuron (LMN) lesions: Presents with hypotonia, hyporeflexia or areflexia, and muscle atrophy.

Neurological Problems & Syndromes

Includes conditions like stroke, seizures, migraines, and various forms of encephalopathy.
Recognition of symptoms is crucial for proper classification.

Neurological Skills

Clinical skills involve cranial nerve assessment, sensory examinations, and reflex testing.
Important clinical tests include Tinel's test, Phalen's test, and assessment of cognitive functions.

Coma Algorithm

Differentiates various causes of coma based on clinical symptoms and history.
Diagnosis guided by alterations in consciousness and neurological signs.

Carpal Tunnel Syndrome (CTS)

Symptoms include numbness, burning pain, and muscle atrophy in the hand.
Tests such as Tinel's and Phalen's assess for median nerve entrapment.

Headache Types

Secondary headaches can indicate serious conditions like subarachnoid hemorrhage (SAH) and meningitis.
SAH often presents as sudden, severe headaches, frequently associated with altered consciousness.

Neurological Investigation

Encompasses imaging studies and other diagnostic tools to visualize and understand brain and nerve function.
Vital for assessing underlying neurological disorders and crafting treatment plans.
