What does neurasthenic mean?
Neurasthenic is chiefly an adjective meaning characterized by neurasthenia, a medical label used in the late nineteenth and early twentieth centuries for a cluster of symptoms including fatigue, weakness, irritability, poor concentration, and vague physical complaints. As a noun, a neurasthenic was a person described as suffering from those symptoms. Because neurasthenia was influential but never a sharply defined disease entity, the term is now mostly historical or literary rather than part of routine clinical language. In modern use, calling someone neurasthenic is usually retrospective, nostalgic, or occasionally critical, and it may suggest nervous exhaustion rather than a diagnosable condition. The word can still be useful for reading nineteenth- and twentieth-century literature, where neurasthenia was linked with overwork, emotional strain, and modern urban life. It also illustrates how medical vocabulary changes: a once-authoritative diagnosis can become a cultural shorthand for fragility, anxiety, and depleted energy without carrying a precise medical meaning today.

Where does neurasthenic come from?
Neurasthenic entered English medical vocabulary in the late nineteenth century through neurasthenia, a compound formed from Greek neuron, meaning “nerve,” and astheneia, meaning “weakness.” The term initially described a supposed condition of nervous exhaustion and weakness that was widely associated with modern urban life and overwork. Related English forms such as neural and neurotic share the neuron element, while asthenia preserves the sense of weakness.
